CoinHI Pillar of the Community United States 2731 Posts	Posted 05/09/2022 03:19 am This looks to be an "Intrinsic metallic inclusion" error as there is what looks like possible streaks of tin or zinc on obverse and reverse. It also looks like the I in liberty got wiped out by grease possibly? Opinions welcome, thanks! "Pride is yoked with callous behavior, as humility is with compassion."

Dearborn Moderator United States 95526 Posts	Posted 05/09/2022 08:37 am Well that is interesting. A poor mixing of the alloys? There is a 5% mix of tin and zinc mixed in with the copper.....

CoinHI Pillar of the Community United States 2731 Posts	Posted 05/09/2022 1:27 pm Thanks, I've seen examples of this on error-ref but never came across one in hand. Interestingly, I found another example on a LWC that I'll try posting later. "Pride is yoked with callous behavior, as humility is with compassion."

Cujohn Pillar of the Community United States 7174 Posts	Posted 05/09/2022 4:10 pm You will see a a few of them going through unc Lincolns. I'm more interested in the area above the I. Looks like more than grease. Small lam? missing metal? Report this Post to the Staff
silviosi Pillar of the Community Canada 6244 Posts	Posted 05/09/2022 4:42 pm What it is the weigh? Seem to be bronze not brass which was normal for this year 75 CU and 25 Ni. I will bath for not more then 1.5 hours in methylic alchohol or alternative= white alchohol 90%. DO NOT PUT IN ACCETONE!. We will see then. Report this Post to the Staff
CoinHI Pillar of the Community United States 2731 Posts	Posted 05/10/2022 03:01 am Thanks Cujohn, so these streaks are somewhat common? That area on LIBERTY could be a lam you're right. Silviosi- weight is 3.12g. I had already used acetone on it and it didn't seem to damage it any. "Pride is yoked with callous behavior, as humility is with compassion."
