"Mint Finder"

[kanderna]

Recently my parents blessed me with all of my old cards and all the etc. that comes with them that I left at their house. Going through it, I found these. A set of 1987 Mint Finders. The intent is that you drop your card down into the Mint Finder and you can determine how well-centered your card is. Has anyone ever seen/heard of these? I imagine they are destined for the trash, but thought I'd check in here to see if anyone has any opinions.

Ive never seen or heard of those before. Im not sure if they are worth anything, but im sure some members here may be interested in them.

Just going to bump this once in case any other thoughts.

Never heard of, nor seen, them before. However, what you said about them, sounds like their intention was good (helping collectors determine how good the centering of their cards were).
