Moneciarz is a portal for coin collectors. Keep an inventory of your collection, record what you paid and the condition of each piece, browse the coin database and follow precious-metal prices — all in one place.
Easily add coins to your collection, manage them and track their value over time.
A catalogue of coins broken down by mintage — year, mint, metal and quantity struck.
Current gold and silver prices in PLN and USD, per ounce and per gram, sourced from NBP and the LBMA.
Import purchase history from popular platforms: Allegro, OLX, Numimarket and more.
Know the value of your collection - both numismatic and metal value (gold, silver).
We use multiple sources and algorithms to ensure the best information about coins.
Adding coins to your collection manually will always be free. Only import features from shopping platforms are paid (20 PLN per import type).
Coin information comes from the auction catalogues of the Polish Numismatic Society (PTN). Over time we want to combine several sources — catalogues, auction results and shop listings.
