What is the value of Schoolboy Rowe jacket from the Detroit Tigers?

Answer 1

If the jacket was owned or used by Schoolboy Rowe it could be worth a couple of hundred dollars and up depending on a few unmentioned factors. The value of the Jacket would rely on if it is a reproduction, authentic game issued or game used. Proper tagging will help identify the later two. A game used jacket could also be identified and authenticated by player attributes.

Player Use Attributes denotes that a bat, uniform or piece of equipment has evidence of player use. For example a number written on a Baseball cap can be attributed to player that wears that uniform number. A baseball bat can have a tape pattern that is attributed to a particular player.

A game used jacket would also be valued by the Provenance that accompanies it

Provenance is the history of ownership of a particular item that allows the buyer to secure additional insight as to the origin or chain of custody of the item. A letter of provenance from a player or team official will be considered acceptable provenance while a letter from a fan or citing that the jersey comes from a particular collection is not.

Without provenance a professional authenticator will have to use tagging, player characteristic, and company shipping records to identify a game issued or game used uniform jacket, and the value will be less. If the jacket is not authenticated then you just have a used vintage jacket and it will be valued as such according to the condition.
