Centennial was established over twenty years ago to provide numismatic and philatelic auction services.
**Changes in technology have made our fax machine land line obsolete.
That phone number is no longer in service.
Absentee bids or contact with Centennial is via email, directly on our web site, social media, text, by traditional snail mail or an actual telephone call.
We apologize for any inconvenience.**
There are no upcoming auctions at this time.
