Bullion gold


We have reached the 100,000 currencies appraised by our experts. We have a large customer base for rare English, German, Swiss, American, French and colonial currencies.


We buy and sell all the world's currencies, from all eras (ancient, Roman, Byzantine, royal, modern). We are also interested in all types of rare banknotes, tokens, medals, and military decorations.

Bullion gold


As for gold, we specialize in $10 and $20 American coins, 20 Napoleon francs and 20 Vreneli Swiss francs. We also attach great importance to first-class gold, which is verified by three experts in Luxembourg and is of a much higher quality.


This type of gold can be traded with bonuses. For example, the bonus for American currencies is currently low, but used to go up to 150% in the 1980s.
