What makes us worth it?

  • We have been operating on the numismatic market since 1989
  • We offer professional advice and specialist assistance of experts
  • We cover all sales-related administrative fees
  • We issue bills of sale and invoices
  • We guarantee comfortable conditions and discretion

 We often ask ourselves whether the coins that have been in our family for generations or  the ones which we inherited are of any collector’s value. The value of a coin is not dependent on its age; numismatic coins that are just a few years old might be way more expensive that much older items. If the coins or banknotes you own are part of a collection, then it is highly likely that there are valuable items among them.

In the case of collector’s items, the price is mainly influenced by their condition. Coins, banknotes and other items in perfect condition might be very costly, and at the same time the value of the same coin in circulated condition might be very low.

Under no circumstances should you clean or wash the coins, banknotes or other items you would like our experts to valuate.
