Coins are struck not printed. Paper currency is printed. Without pictures we can't give a 100% attribution. But sounds like a normal Struck Through Grease. It's a filled Die minor error Worth.. 25C
Honestly if you put it on eBay as a "grease filled die error" someone may pay you a couple bucks for it. That's about all you can hope for, IMO.
True.. I saw a Quarter on eBay that said IN GOD WE RUST.. Missing the T go for more than $30.00 ridiculous!
Ok, but not if that's what they want... so maybe the guy that bought the "In God We Rust" 25c works at a junkyard and wanted to get it to make a plaque in his shop... I mean, people buy what they want sometimes.
That may be true, but when the time comes for the heirs to try to dispose of his "errors", they will probably get laughed out of the coin shop. Chris
