I just decided to sell some things taking up too much wall space. I listed them on Craigslist and eBay but here's what I have with my bottom dollar firm prices (listed for more elsewhere for negotiating). I'm certain the COA is legit as I knew the shop owner. Unfortunately it's not the big name (Steiner/PSA) that people like, this the discounted prices. The COA comes from Terry Bender promotions who's still in business today. I'd pkg them both for $900. They're both wrapped and encased so mint condition signatures as well.
1996 Yankees team bat. 23 signatures (Jeter, Rivera, Torre, etc) and a COA $650
1996 Yankees World Series stamped ball with 17 signatures (no Rivera, but Jeter, Torre, etc). $350
