Found my second honey hole that nobody has hit and remains a secret. Lots of trash, but plenty of coins. It's a old football field that was build in the mid 50's. Found 3 wheaties, 47D, 57D, and a 55 (wish it was the double die, but it's not). Told myself I wasn't going home till I found silver, not but 10 min. later comes out a 64D dime in, from what I have read and looked at, I would say it's EF-40. Looks like they lost it the same year. For my prize find, this coin was 6 plus in. deep standing on edge. It is a 1968 Finland penny. On the back it says 1 penny and on the front it says SUOMEN TASAVALTA. I have no idea how it got to South Dakata, but I'm glad it did. Is this a rare find? Thanks John from Australia for the tip, it helped alot.
