Ivy said previous golf items through Heritage included the original Augusta National green jacket of co-founder Bobby Jones that fetched $310,000.
Other high-end golf items were Walter Hagen's gold medal from his 1922 British Open win at Royal St. George's and Ralph Guldahl's gold medal from the 1939 Masters. Each went for $65,000.
Jack Snead said the proceeds would likely to go charity.
"The trophies didn't mean that much to Pop in a way,'' he said. "In those days, he was more concerned with the pay check. The thing he was most proud of was his record. He cared more about than any of his tournament wins.''
Jack Snead said there were some items that would never be sold at auction, though they weren't all related to Sam Snead's golfing career. He mentioned the tractor that his father rode on his farm in Virginia to relax when he was away from golf, some of the guns he had since he was a boy growing up in West Virginia, and the five-string banjo he played.
For Heritage Sports, there wasn't as much work involved in authenticating the items. Sam Snead did that himself.
His son said when they used to display the items in Sam Snead's Taverns, his father thought it would be a good idea to write a note explaining the significance of each.
"The provenance is much better coming from the family of an athlete,'' Ivy said. "That's something Snead did that I've never seen done before. He went through and numbered all the clubs he owned - the significant ones - and wrote letters of authentication of each club. We've got handwritten letters from Sam Snead saying, 'This is the club used in 1954 in the playoff with Ben Hogan to win the Masters.' He's got literally hundreds of those.''
Other items being offered in the initial auction include the putter Snead used in the 1954 Masters; the red captain's jacket he wore in the 1969 Ryder Cup; the Wanamaker Trophy from his 1951 PGA Championship victory at Oakmont; a Ryder Cup trophy from 1959; the gold medal from his first Masters win in 1949; and a silver medal from the 1947 U.S. Open. The U.S. Open was the one major Sam Snead never won. He lost in a playoff to Lew Worsham in 1947 at St. Louis Country Club.
"It's a pretty exciting collection,'' Ivy said.
