Found a little while back,there was only a few minutes left so I decided to risk it.The photos are poor but to me it appears to be some kind of overdate especially around the(6).If it isn't an overdate I did pretty decent for 30 bucks otherwise.
I am not real sure what you have but it's a goody! congrats, I'll give ya money back in a heartbeat lol
About an average price, and there are no overdates for this year. There is a repunched date N-19, but this isn't it. N-19 has an italic 5 and this is an upright 5.
I think it's N-20, but the focus is off just enough that N-8 can't be ruled out. The clash is strong and the date looks even closer to the dentils which is probably from lapping and die deterioration.
