The Red Sox may be the Yankees’ hated rivals, but that isn’t stopping them from cashing in on Derek Jeter’s accomplishments.

The Sawx are auctioning off the ball used to record Jeter’s last out at Fenway Park — a liner to short on Sept. 28 — and bids have reached over $7,500 with hours to go. The Bosox are also auctioning the first-base bag that was used when the now-retired Yankees captain got his last hit, an infield single. The bidding has crossed $15,000, but an unspecified reserve hadn’t been met.

The items are being auctioned through Major League Baseball’s in-house auction website.

Both auctions are set to end at 8 p.m. ET on Monday.
