About Us
Bidsy is an independent analytical platform for the numismatic market. We build an organized, proprietary database of historical coin and banknote transactions, enabling collectors to analyze price trends and compare market parameters.
Our goal is to provide analytical tools, statistics, and summaries that help collectors make informed decisions.
Data presented on the platform:
- comes from publicly available information about completed auctions,
- is processed and organized according to our own classification structure,
- does not include photographs or full listing content.
The platform does not sell numismatic items and is not affiliated with any auction platforms, including Allegro or OneBid. Their names are used solely for informational purposes in the context of historical transactions.
