SPECIAL AUCTION: Hoppel Collection RARE SPECIES & CLASSIC MINERALS
Mineral Liquidation Auction

NOTE SPECIAL END DAY: TUESDAY July 28th, 2015
at 6 PM (Central Time Zone)!

In partnership with one of the world's largest auction companies, Heritage Auctions of Dallas, we are honored to present the second megasized set of several large auctions of rare species and fine locality pieces and classic mineral specimens from the massive Hoppel Collection. After several years of holding back many rare species and more sophisticated collector specimens from the Hoppel collection, Heritage and I have negotiated a deal to let me offer these specimens to my customers via our own auction style. Bidding starts at $10 even though many specimens are valued at $1000 and more! We are excited that these liquidation auctions will bring to market hundreds of specimens of importance to collectors, many from the 1980s and 1990s heyday of mineral collection dispersals!
