Can you imagine examining a coin from the 5th century BC in 3D from your computer, or check the authenticity of a piece with a click thanks to the blockchain? Numismatics is no longer just a magnifying glass and gloves: technology is transforming how we collect, study and preserve historical money. Here we tell you about the most fascinating innovations, supported by institutions such as 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, such as those used by the Biomedical Engineering faculty at Harvard University In research projects, they allow the creation of digital replicas of coins with precisions of 0.01 mm. This not only helps detect counterfeits, but also democratizes access: platforms like Sketchfab They house 3D models of Roman or Greek coins to study without risk of damaging the originals.
actual example: In 2022, the Numismatic Museum of Athens digitized its collection of old drachmas, and now anyone can “drive” them virtually!
2. Blockchain: Fraud-proof certification
Did you know that companies like NGC Do you already use blockchain to certify coins? Each piece receives a Unique digital ID stored on a blockchain. This eliminates forgeable physical certificates and allows the provenance of a coin to be traced in seconds. Up to 45% of collectors prefer pieces 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 from 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 success rate exceeds the 92% in common currencies.
4. Digitization of catalogs and collections
Museums and auction houses such as Heritage Auctions have digitized millions of records. This not only preserves history, but also helps collectors compare pieces from home. For example, the US Library of Congress offers free access to its digital numismatic archive with more than 1.2 million entries.
5. NFTs and virtual currencies: The future of numismatics?
Although controversial, NFTs (non-fungible tokens) are opening up interesting debates. In 2023, the UK Mint has launched a limited series of NFTs tied to special edition physical coins. Will they serve to authenticate physical pieces? CoinDesk They believe so, as long as 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!
