Congrats! I went over a year before I finally found my first Indian, then, they started popping up all over! Hope it's the same for you.
I invested in a small ultrasonic cleaner. It's was not expensive, maybe $35.00 or so. It mainly just cleans out all the dirt on and in the coin.
Often then the coin or relic feels a little rough, because the dirt has eaten pores into the metal, but a coat of wax will bring that back to feeling smooth
and protect it from any other oxidation.
With non-valuable coins you can get a little more aggressive if you want, I think that coin will clean up pretty well. (PM me if you want to know what I mean by "aggressive")
Good luck and congrats again! HH.
