Hello.

The coins in question are the first Lincoln cent weighing as 2.5g, and it has some sort of build up on both the obverse, and reverse. The second coin which is a 2000 and is much thicker than the other 2000 cent which is beside it in the photo as a size comparison, and the coin in question weighs 2.41g. Can someone help me with any additional information with these two coins.

Thanks in advance. Attached Files
