Several people who attended the Kobe Bryant memorial at Staples Center are selling souvenir items from the event ... from ticket stubs to program booklets ... and the asking price is in the THOUSANDS of dollars.

We've already found a handful of listings on eBay from people selling their memorial pins, shirts and other items. Most of the listers claim they personally attended the event.

The average starting bid for the Kobe Memorial bundles are around $3,000 -- with a $5,000 "Buy It Now" price.

One seller listed an official Kobe shirt (size XL) from the memorial -- and after receiving 76 bids, it sold for $2,025!

Remember, most fans were only able to get tickets to the event by entering a random drawing. If they were selected, they had the option of buying tickets for either $24.02 or $224 each, with the money going to the Mamba & Mambacita Sports Foundation.

Some fans flew from around the country to be at the event -- and they could be selling the giveaways to help offset the travel costs.

Other people feel it's BAD FORM to auction off items from a memorial event -- and those people have been very critical of the sellers.

One thing is for sure ... Kobe items are in huge demand right now -- from autographs to game-worn jerseys and even his 8th-grade yearbook. And, as long as there are people willing to shell out the cash, there will be no shortage of supply.
