Wilt Chamberlain Rookie Uniform Hits Memorabilia Stock Market, Valued at $1.2 Mil

The uniform Wilt Chamberlain rocked during his DOMINANT '59-'60 rookie season is about to hit a sports memorabilia stock market ... but don't stress if ya ain't rich, 'cause you don't need a milli in the bank to own a piece of the threads.

It's a new way for people to own a piece of history without breaking the bank -- with the same kinds of risks and rewards as buying stock.

Here's the deal ... the person who currently owns the Chamberlain uniform is David Kohler, who runs the wildly successful SCP Auctions company, which specializes in high-value collectibles.

Kohler tells TMZ Sports ... Wilt rocked the items for every home game during his rookie season with the Philadelphia Warriors.

The items have been authenticated by the widely respected MEARS evaluation company and photo matched by the folks at MeiGray Authentication, Kohler says.

Kohler has owned the piece for years and has decided the time is right to sell -- so he teamed with the app Collectable to make it happen.

The Chamberlain uniform will hit the market on Tuesday -- with an Initial Public Offering (IPO) backed by the Security and Exchange Commission.

We're told there will be 95,620 shares available for purchase at $10 a pop -- and from there, you can monitor the value like you would a typical stock.

Kohler says he's retaining 25% of the jersey -- which would bring the value of the item to $1.275 mil.

Collectors can buy as many shares as they want ... and resell them (hopefully for a profit) on the Collectable app.

Chamberlain -- who won Rookie of the Year -- averaged nearly 38 points and 27 rebounds per game. No, not a typo ... the man averaged 38 and 27 as a ROOKIE ... in what's likely the greatest 1st season in hoops history.

Blocked shots weren't calculated at that time ... but you can bet Wilt's blocked shots per night would've been absurd, too.

Kohler tells us he believes the Chamberlain uniform is one of the most coveted in sports history.

"This is one of the finest game-worn uniforms known to exist in the basketball memorabilia industry. His rookie uniform, supported by photo documentation that is unprecedented for its era, ranks not only as the finest basketball uniform in the world, but one of the finest uniforms from any sport, period."

Wilt went on to have an absolutely remarkable career ... making 13 All-Star teams and winning 4 league MVP's before being inducted into the Hall of Fame in 2006.
