About Plato Auctions

A respect for the objects that highlight our history.

Plato Auctions was founded more than 25 years ago by Don Plato. The company was born of an interest and passion in the objects that tell the tales of times past. Having had a trained eye for historical and unique pieces, Don began considering his career by gaining experience as a successful antique dealer at regional Auction Shows.  this experience later led Don to becoming an auctioneer at a young age; Plato Auctions was formed and has been a force in the auction community ever since.
