Error Coin Question

[fingerscrossed]

Hi Guys,

hope you are all doing well. I haven't really been posting anything lately as I have been a little inactive with CRH.
Today I just got a box just fill in the gap..I found the picture below I believe its an error coin but I don't really know
much about it. Sorry the cam is pretty crappy but in this coin there are 3 dates, the usual date is 1981 D mint.
there are two more dates on this coin, on the left is 1960 and on the right is 1980. Can someone please tell me something about this coin?

Thanks!

Others on here can tell you more about it, but I have about a half dozen of them I've found CRHing.

It is the result of third party marketers to commemorate 20 years anniversary. They sold them for a premium of $4.95/each. In some cases, they are gold plated or chrome plated. They were so successful at ripping people off that they also attempted a 25 year anniversary. Keep it as novelty or throw it back.

It commemorates the 20th anniversary of Kennedy's win over Nixon in the 1960 Presidential election. A private company over-stamped "In God We Trust" with the years 1960 and 1980, then dipped the coin in gold leaf (not enough to add any value). Sorry, but it's worth 50 cents.
