I don't think they are common. There is probably a different term for what you are seeing on the coin but I'm not sure what it is.
Honorable mention goes to everyone who voted 64... idk how this got a 63 other than it being an old holder and the few planchet flaws/lamimations on the coin
LD idk if thats what they are either... i just dont know what else to make of.them.. they dont look like hits but ive been wrong b4
I knew what the grade was because I recognized the coin as one that I once owned. It's a nice strike with a decent cameo. The uneven toning on the reverse is the result of a poor mixture of metals in the planchet. It's pretty common and can really develop some nice color over time. The 1892 below has a similar planchet problem.
Thanx for chiming in kirkuleez... I picked this out of the crowd 'cause of the 2 things you mentioned actually(nice doubling too)... I believe you when you say u owned it because the feller i bought it from is obviously well traveled and does the bigger shows judging by his inventory (alot of classic proofs) and he only comes around here once a year for THE annual show
I can't remember who I sold it to, but it was about five years ago at the Whitman show. I also believe that I was the one who sent it in for grading.
