Sources & photography

Follow the evidence

Each record includes its sources: maker announcements, product specifications, auction descriptions or collector references. These sources can describe different specimens, editions or moments in a product’s history. We identify those distinctions where the evidence allows.

A year on an object is not always its release year. An announced edition limit is not necessarily the number produced. A seller’s description is not independent authentication. Identification notes explain known conflicts and limits; details that are not established remain unknown.

Original prices and early offers

We record original issue prices when a dated maker or issuer source supports the specific issue and variant. Original retail prices identify the seller separately. A historical maker offer is labelled as such when the evidence does not establish the launch price. An edited announcement does not necessarily preserve its launch-day price.

Prices are per the quantity and version described, in the original currency. We identify known tax, shipping and Bitcoin funding terms; unstated terms remain unknown. Face value and stored Bitcoin are not the purchase price. These are documented asking prices, not proof of a completed sale or a current market valuation.

We do not treat a current shop price, a sold-out listing without dated price evidence, or an auction estimate as an original issue price. We do not convert historic BTC or foreign-currency prices using today’s exchange rate. Missing prices remain undocumented until supporting evidence is available.

An archive in progress

NUMISATO is an independent reference for physical Bitcoin coins and collectibles. The published records are not a complete list of every issue or variant ever made. We continue to reconcile source inventories, distinguish variants and add missing photographs.

A photograph may show an example of a type rather than the exact variant in a record. Check its caption and the identification notes. An image does not establish a collectible’s authenticity, condition, ownership or current Bitcoin balance.
