Heritage Auction Galleries has reported the private sale of “a pristine condition copy” of Flash Comics #1 for $450,000. The company said the March 12, 2010 was completed through their new “Make Offer to Owner” service, which is designed to unite successful bidders from their earlier auctions with eager new buyers.

“The seller had originally obtained it for $273,125 in a January 2006 Heritage auction, and the buyer initiated this latest purchase directly through the new (MOtO) feature available in Heritage’s Permanent Auction Archive at HA.com,” the company said in a press release.

The CGC-certified comic is graded 9.6 and comes from the Edgar Church – Mile High Collection pedigree. The names of the buyer and seller were not released.

Heritage, of course, recently set the record for selling the world’s most valuable comic book at $1,075,500 for Detective Comics #27.  The auction in which that sale was included broke Heritage’s own Guinness World’s Record with a total of $5.6 million.
