I have a penny from 1968, in Philadelphia, and it looks like it is a proof coin somehow. Proof coins have a certain coating on them, and this looks like one of them. This could possibly just be an uncirculated coin though. The picture doesn't demonstrate what I described, so I won't upload them.
I do know what you mean. There is a coin state for non-proof coins that is called Proof-like. The designation is PL.
Post the picture anyway. A Lincoln proof is easily identifiable versus an MS cent, even a PL. I’m not sure what you mean by a certain coating, but we’ll be able to tell if it is a proof or not.
If it's a philly then not a proof,special mint sets did stop in 1967 and for the late 1960's.The mint had some pretty nice dies for 1968 phillys.Your coin could be just a very exceptional early strike with some fairly new dies.High gem phillys from this year tend to be very nice and possibly proof like but not exactly.Or your coin might of had human alteration,polished and plated coins can resemble a proof sometimes.

I agree with @potty dollar 1878. Probably struck from new dies. Although these dies are not processed in the same way as proof dies, they do produce proof like finishes for the first few hundred or so struck coins.
This has been said but possibly lost in context. Proof Lincolns early on were produced at the Philly mint up to 1964! The next proof minted Lincoln wasn't until 1968, from 68 on proof Lincoln's were minted at the S.F. mint. So, at best you have a High Grade MS coin.
