One of the most important pieces of memorabilia from Victor Wembanyama's NBA career -- a jersey he wore during his first-ever Spurs game -- has just gone up for auction ... and so far, bidders are showing they really want the item.
In its first day on the block, the threads that the 19-year-old phenom rocked in San Antonio's season-opener on Oct. 25 have already received 25 bids .... with a high $50,000 so far.
Experts at Sotheby's -- which is hosting the auction as part of its new partnership with the NBA -- previously anticipated the jersey would sell for between $80,000-$120,000 .
