Numismatic Guaranty Company (NGC), Numismatic Conservation Services (NCS) and Paper Money Guaranty (PMG) have appointed The Bolaffi Auction Group, a leading numismatics firm in Europe, as an Official Submission Center in Italy and Spain.

The Bolaffi Auction Group traces its roots to a philatelic business founded by Alberto Bolaffi Sr. in Turin, Italy, in the late 19th century. Aste Bolaffi later expanded to coins and today is one of Europe’s leading auction houses. In 2018, Aste Bolaffi purchased two other prestigious auction houses: Soler y Llach International Auctions, founded in 1989 and based in Barcelona, Spain; and Harmers of London, founded in 1918.

The Bolaffi Auction Group affiliates hold several major numismatic auctions a year. As coins and banknotes are increasingly sold in online auctions, it has become even more important to offer customers accuracy, transparency and peace of mind. The Bolaffi Auction Group is providing greater confidence and security to the marketplace by working more closely with NGC, NCS and PMG — three companies renowned globally for their expertise and impartiality.

NGC was established in 1987 to provide expert, unbiased assessments of the authenticity and grade of coins, tokens and medals. It has since certified more than 53 million collectibles. NCS, a professional coin conservation service, has conserved more than 1 million coins since it was founded in 2001. In 2005, PMG was established to provide similar grading services for paper money and has now certified more than 7 million banknotes.
