Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
Quite a few different McGwire limited edition plaques and collages were issued that year, by various third-party makers, so I'd need to see an image of yours to properly value it. Please provide an overall photo and a close-up of any autograph(s).
You can use the paperclip icon on the tool bar above the reply box to post a photo. If that's not showing up, let me know and I can give you other photo options.
