Im not an expert, and I hope I am not right for your sake, "my opinion" due to the bag marks, plate lines out of back of head, and other factors, but mostly the mirror finish on the lower part of the rim of the last picture you supplied I am going to say a "freshly" 3-4 micron thick rhodium plated cent. rhodium is expensive but very common in plating jewelry (or just about anything) as so little is used. it is extremely hard, and holds that mirror finish. most any jeweler "should" be able to tell by actually looking at the coin in hand if it is rhodium plated.
