Time to Part With My Tigers Heritage Collection in Detroit Tigers Baseball Cards Posted July 3, 2018 I am hesitantly looking to sell my collection of Topps and Bowman Heritage cards. I have sets from the first through this year. Includes ROAs and buybacks. Hundreds of base and SP cards are autographed in blue Sharpie— numerous Kalines, Miggie, Fielder, Porcello, Scherzer, and one Verlander. Can anyone estimate what such a collection is worth? Thanks!!!
