We'll need to know the set it's from and the complete checklist to get it added. Please refer to the FAQ regarding "How do I add a set to the database" https://www.tcdb.com/FAQ.cfm?ITEM=AddSet.

Note: Please see my profile for more info regarding trading (section updated 10/25/2023). I have added a large portion of my inventory to the site, and currently have trading turned off (details are in my profile). I have (finally) unearthed my 2 very large boxes of Star Company minor league sets and they are available (email for details).
