Which is the largest coin auction house?

Heritage Auctions (ha.com) is the world's largest collectibles auction house, handling over 200,000 numismatic lots per year. Their free Heritage Archives database of past results is the most valuable pricing research tool in numismatics.

What is the typical buyer's premium at coin auctions?

Major houses charge 17.5-20% buyer's premium on the hammer price (verify current rates as they change). GreatCollections often has lower premiums. Always calculate your total cost (hammer + premium + tax + shipping) before bidding.

Which auction house is best for beginners?

Heritage Auctions offers the best starting point — its volume ensures you'll find coins you want, the Heritage Archives provides extensive research, and weekly Sunday Internet Auctions offer affordable, no-reserve lots perfect for learning the auction process.
