very nice find! Good detail! I personally would use baking soda and a toothbrush to remove stuff around edges but I don't think you need to do anything to coin.
That's a really nice key date coin! Ya don't see too many on here like that. I'm voting banner. I'd like to see a two cent piece be on the banner. Big Congrats!! Hogge
Wow, very nice condition 2-center you recovered. I'd either leave it alone cleaning-wise, or have a professional do it and grade it, but that's just me. With a condition that good, I would hate to do anything which might compromise the condition in any way.
