If you found that Indian from your old farm dump site there will deff be more. That site you have looks amazing and a ton of fun.
If you get another green Indian, or wheat penny or even large cent try heating up some peroxide and then drop the coin in it. It really does a great job getting the green corrosion off without damaging the coin. Electrolysis works great on silver coins with gunk but it chews up copper coins.
what year was it? 1889? i see 188? I think..
It's one more Indian than I have found
