Good question. Not sure if you could get an honest diffenitive answer based on oppinions. But the book says don't clean. Ruins value
@Kyziefly ...better pics are needed, can't help you from blurry photos. Jim...in general, polishing and cleaning only help to lower the value of a collectlble coin. To remove organic debris, acetone baths are considered non-damaging...Spark
these were coins ive bought over the past 30 years the seated half I use as my logo is one in question sorry I don't have any other pictures
The title is 1962. Blurry photos of a D mint mark. Photo of circulated 1964-D Lincoln cent. Photo of AU 1964 Lincoln cent. I get it, you are just putting in your 2 cents. Good one.
