So after searching another $190 in halves, I found 8 silver coins (including 1 1964), a 1983 proof, a Dutch coin from the 1970s, and a few other weird finds: 1. 1996 Kennedy - portrait is very clear, but everything around it (LIBERTY, the date) is very worn. This is probably a greased die error. Is this worth anything? 2. 1971 Kennedy - very wide rim, it looks like a proof but it has no mintmark 3. seven 1972 Kennedys that look like proofs, but no mintmark 4. 1979 Kennedy that again looks like a proof, but no mint mark Are any of these worth keeping?
They are all worth keeping if you collect coins because you like them. If you however your goal is to make a profit then keep or sell the silver ones to a coin shop for silver value and spend the rest.
if those proof like coins don't have a s mintmark, they are not proofs, but uncirculated. as for the 1996, grease filled die, i would keep it.
How much would you say a greased die error is worth? I don't collect error coins, so I would want to sell it if it's worth anything.
The ones with prooflike qualities were very common early in the series and were the result of overly polishing dies to be reused. The 1983S proof is a nice find. As for the 1996 one, this could also be caused by the coin rolling equipment. You need to post a pic if you want a paraprofessional opinion on the cause of what you are seeing. Until you are convinced otherwise, treat it like it's a genuine error. We are all learning everyday and don't be embarassed if it turns out to be post mint damage. I once held onto a 1971 Kennedy half for a few years that I was convinced was an error with the metal. It turned out that some acid treated the coin to remove the nickel to give it a copper/brass look. It was a real let down when I learned that.
