What Is A Minor Doubled Die Really Worth?

I'm in the same boat as coin frog, if it's not visible naked eye it's a spender.

I've sold many full rolls of varieties over the years, and the feedback I've received is that the buyer purchased as an investment, with the roll going into a collection rather than being sold for profit. Not one of the buyers said they were buying to resell.

On the flipside, I've been a strong buyer of BU Wheat rolls for decades, and in that pursuit have purchased quite a few rolls that were solid RPMs, Doubled Dies, BIEs, filled letters, minor errors, etc, usually all one type. Since I search rolls for these things, it's always an eye opener to find an interesting variety on the first coin, then the second, then third...!!!

Good luck Uruman!
