Diy Tips To Clean And Refurbish Ancient Coins

There is a whole art and established practice behind cleaning and restoring ancient coins and artifacts. In fact, there have been decades of tools, tips and tricks, rubs, solutions, and waxes used to clean old coins on one’s own but with professional quality – especially coins that are no longer issued. Here are some tips to consider and start with.

Use mild solutions

In cleaning and restoring coins, you shall need basic tools and materials, such as a polishing wheel and water in a spray can. Simple preparation involves using a weak soap – anything that isn’t detergent – solution in distilled water to remove dirt and grease from an encrusted coin. The goal is not to inflict any damage on the upper-grade coins, especially when using harsh chemicals. If a coin is heavily encrusted, it can be soaked for a couple of months in olive oil, which won’t damage the coin further but instead dissolve the undesirable crust.

Avoid destructive cleaners

These solutions use abrasives or acids that clean and actually alter the coin surface. Widely advertised metal cleaners, for instance, are likely acid-based ones that remove some of the surface metal in the cleaning process. Avoid them to preserve the coin’s collector value. It’s also best to avoid over-cleaning so as not to diminish the coin’s value, and to stick to the least abrasive techniques.

Be patient

It will take time to clean ancient coins, and those that have more difficult deposits will require further work. There may also be multiple methods to get them sorted out. Soaking the coins in distilled water, for instance, may be a slow process and can take months, but will loosen dirt effectively without introducing damage. When in doubt, seek professional help for coin cleaning and restoration.

Intriguing Recently Discovered Artifacts

Even in the new millennium, artifacts are still being discovered and excavated throughout the world, priceless testaments to mankind’s religiosity, innovativeness, and even dark past. Here are some of the more recent artifacts that have been unearthed.

Earlies buddhist shrine in Nepal

Archeologists digging through a central shrine in Nepal were surprised to find an old wooden structure beneath the modern, brick-building monument. The design is very similar to the new version atop it, but the discoverers were intrigued that there was much foot traffic on the clay floor and that there were post holes on the tree roots. The finding was dated to about 550 B.C. and is now thought to have huge implications on when Buddha was actually born.

The Beardless Jesus

An excavation in the ancient city of Castulo in southern Spain revealed images in discovered glass shards that, after collation and assembly, showed a truly intriguing plate. This plate is believed to serve the eucharistic bread and showed a beardless Jesus donning a Roman toga. The apostles Paul and Peter were also depicted clean-shaven, their hairs cropped short. It’s now considered one of the earliest images of Christ to have been discovered.

The Crucifixion bone

For decades, there have been no physical evidence discovered of the popular and well-documented Roman execution method of crucifixion. But archeologists recently found the bones of a man in a museum in Israel that now serves as the only documented proof of this harrowing punishment. The young Jew was in his twenties, and there is an iron nail embedded deeply into the man’s heel bone.

A Look At The Artistry Of The Byzantine Empire

The Byzantine era is one of the most interesting periods in human history. A lot of stories about those centuries have made their way into legend and lore. Another popular aspect of the Byzantine Empire was its culture, with artistry inspired by religion. The art, though mainly traditional and controlled by the church, gives everyone an insight into how the world was run at the time.


Image source:

Art critics and historians note that Byzantine art is both religious and conventional, with paintings in fresco and illuminated manuscripts. They were also found on wood panels wherein mosaics were the most well-known medium. Sculptures at the time were rare, with a few carved ivories being the only exceptions.

However, as conventional as Byzantine art was, it was extremely popular for those who could afford it in Western Europe. The classical realist style became the main influence on medieval art, which in turn formed a huge part of the foundation of Italian Renaissance art.

Art historians also noted the exceptional originality of Byzantine art having a minimal influence unto itself, with the Eastern Orthodox church being its main contributor. The influence of Byzantine art stretched far beyond Italy and extended all the way to Egypt, Arabia, and Russia.

How To Authenticate Ancient Coins

Forgeries of ancient coins are believed to be as old as coinage itself. Thus, learning how to authenticate coins in one’s ancient coin collection is also a timeless skill, one that requires knowledge, experience/exposure, and research. Often a visual inspection will do, but sometimes more sophisticated tests are done in difficult cases.

A genuine coin, for starters, is made of the correct type and density of metal. While a silver dime is made of silver, a gold dollar is made of at least 14 karat gold. Coins that are produced completely of the right metal or alloy, too, will differ both in weight and density. Genuine coins have a standard mass measurable with a good quality balance, while each metal or alloy has a standard density measurable by simple tests.

For more valuable coins, it is advisable to use a professional grading service. Companies such as the Professional Coin Grading Service offer these services. Dealers also usually offer grading services, although they also outsource the job to the kind of companies mentioned above.

Avoid ancient coin sources, too, that say they know nothing about ancient coins but are guided by a “knowledgeable” friend or have “found it recently in granny’s attic.” There could be sellers offering enticing coins such as Sicilian tetradrachms, of relatively high grade and wonderful listing details. They could also say, however, that while the coins were from a decades-old collection and are believed to be genuine, they are unable to guarantee the authenticity – and they offer no returns.

If it’s too good to be true, it probably is. Learn authentication as an exciting part of the process, where technology and free internet have made it so much easier and convenient.

How To Tell If An Artwork Is Real Or Fake

Forgery, or the creation of rip-offs, is very prevalent in many facets of modern living: from clothes and shoes to high-fashion bags and even art. Paintings are some of the most replicated, and you don’t want to waste that precious money. Here are some tips to ensure that you don’t become the next fraud victim.

First is to study closely the back of paintings or, for sculptures, the bottom. Auction labels and/or auction stamps are often placed in the area. Forgers tend to take these areas for granted and just focus on making the front part look authentic.

Provenance documentation is something you should insist on. This is very important, especially to avoid legal trouble if, say, the artwork turns out to be authentic but actually stolen. In line with this, make sure that the said provenance is exactly for the artwork you’re buying and not just borrowed from some other work. Of course, you’ve to look closely at the document and ensure that it isn’t fake.

It goes without saying that you should only buy from a dealer with a great track record. Buying online can be tempting and is definitely more convenient but being physically present in a reputable gallery is the best way to buy. Finally, requesting for forensic tests is now becoming the norm when buying artifacts and art, so ask for this from your dealer.

Some famous archeological finds that were proven to be fake

It is not uncommon for curators of galleries receiving huge amounts of donated artifacts to find the occasional fake or fraudulent ones. However authentic-looking these antiquities or ancient art are, the keen-eyed gallery staff should be able to distinguish the rip-offs from the truly collectible. But history has seen quite a few bogus archeological “finds.” Here are some of the most popular and most documented.

Crystal Skulls

These famed skulls, thought be ancient artifacts from the Mayan or Aztec societies, were made popular worldwide in an Indiana Jones film. They indeed look both intriguing and fascinating. But Smithsonian anthropologist examining them using powerful microscopes found out in 2005 that the cuts into the crystal showed evidence of modern techniques: both the cuts and grooves were done with modern lapidary wheels, and the skulls themselves were polished using modern machinery. They were created by European craftsmen in the late 1800s and early 1900s.

The Kensington Runestone

A farmer in Kensington, Minnesota, claimed to have discovered stones near the town that showed strange runes. This was in 1898, and more than a century later, scholars who have studied the stone claim that the runes were carved by 14th-century Vikings. However, modern findings prove that the stone was in fact created in the 19th century, and do not match other runes from the medieval era.

The Donation of Constantine

This is a well-documented case of a forged document that has been replicated over and over since the 8th century. It states that Roman emperor Constantine I gave Pope Sylvester I and all his successors ultimate authority over lands controlled by the Roman Empire. This powerful document was excessively used by the said pope during the Middle ages to prove that he held authority over the rulers of Europe. Italian scholar Lorenzo Valla denounced the document in the 15th century.

Art and business appreciation in coin collecting

Coin collecting is a hobby appealing to many. It requires intellect and desire to go deeper into knowledge of the coins, especially as concerns their origin, their previous owners, and other information. Coins transcend generations, and some sets become family heirlooms. Most coin collectors began with their hobby in their childhood; coins are timeless and their collections can only increase in value.


Image source:

For art’s sake, coins are collected for their wide history. Each coin has a story to tell; it tells who was in power while it was in circulation at a certain time period, who the rest of the political leaders were, and if they waged war or preserved the peace.

Collecting coins is a way to appreciate the advent of civilization and the beginning of innovation. A collector learns about the time’s economy, geography, and art from the coins. Ancient artisans crafted coins by hand and every coin gives a collector a chance to witness the brilliance of each coin maker.

Ancient coins are also a form of investment for collectors. For starters, these coins are expensive, and their value increases. While pride and ownership are the main motivations for being a coin collector, the industry of coin collecting is prized at $10 billion dollars in the U.S. alone. Investing in this industry isn’t a short term caprice as it takes years of experience and the process of collecting a set of coins takes years. However, doing so is also very rewarding.

Sometimes, however, hobbies take too much from their practitioners. Having the right motive and desire to pursue one’s interest eventually pays off, especially if it’s an interest in collecting ancient coins.
