Can you imagine examining a 5th-century BC coin in 3D on your computer, or verifying the authenticity of a piece with a single click thanks to blockchain ? Numismatics is no longer just about magnifying glasses and gloves: technology is transforming how we collect, study, and preserve historical currency. Here we tell you about the most fascinating innovations, supported by institutions like the British Museum and experts from NGC (Numismatic Guaranty Company).
Did you know that in ancient Rome, merchants would bite coins to check if they were made of pure gold? Today, blockchain does just that (without teeth)! For example, in 2021, a fake Roman gold coin from the 3th century was detected in seconds with a XNUMXD scanner and certified with blockchain.
1. 3D Scanners: The revolution of millimetric detail
3D scanners, like those used by Harvard University in research projects, allow for the creation of digital replicas of coins with an accuracy of 0.01 mm . This not only helps detect counterfeits but also democratizes access: platforms like Sketchfab host 3D models of Roman or Greek coins for study without the risk of damaging the originals.
Real-life example : In 2022, the Numismatic Museum of Athens digitized its collection of ancient drachmas , and now anyone can virtually "handle" them!
2. Blockchain: Fraud-proof certification
Did you know that companies like NGC already use blockchain to certify coins? Each coin receives a unique digital ID stored on a blockchain. This eliminates counterfeit physical certificates and allows you to trace a coin's provenance in seconds. Up to 45% of collectors prefer coins with this technology, according to a report by PCGS (Professional Coin Grading Service)!
3. Artificial Intelligence: The Numismatic Detective
Apps like CoinSnap (available on iOS and Android) use AI to identify coins with just a photo. The tool compares your image to global databases and returns technical information, market value, and even alerts about potential replicas. According to Numismatic News , its accuracy rate exceeds 92% for common coins.
4. Digitization of catalogs and collections
Museums and auction houses like Heritage Auctions have digitized millions of records. This not only preserves history but also helps collectors compare pieces from home. For example, the U.S. Library of Congress offers free access to its digital numismatic archive with over 1.2 million entries.
5. NFTs and virtual currencies: The future of numismatics?
Although controversial, NFTs (non-fungible tokens) are sparking interesting debates. In 2023, the UK Mint launched a limited series of NFTs linked to special edition physical coins. Will they be useful for authenticating physical coins? CoinDesk experts believe so, provided they are properly regulated.
Technology won't replace the feel of an old coin, but it is expanding its possibilities: from preserving heritage to combating fraud. If you want to be a modern numismatist, embracing these tools is key!
