I noticed that this Hal Newhouser card 2008-11 Monarch Corona Wood Background Series #2 1946 Hal Newhouser | Trading Card Database (tcdb.com) is signed on the back. Did a bit of searching around and found this about the set
"(A very few of each card in the series above are signed on the back by Allen Miller Jr. – who designed them. Miller’s autograph has no real value, but due to scarcity the signed examples are generally considered to be worth slightly more.)"
So I'm thinking, create an insert set for autographs and have the card moved over??
