Check Out My N.i.f.c. Haul From A Fed Box ! & Pics !

Very nice!

I am sure the 1977 Kennedy is plated. The dates signify his election in 1960 and the 20th anniversary of that election in 1980.

You should keep the NIFC coins. You might need them for future trades or gifts for the kids.

They are String & Son Co. wrapped......and the halves are "machine wrapped" and usually yellow paper. They come from the Federal Reserve....so they aren't "bank wrapped" or "customer rolled" or anything like that. And they would come from the nearest Fed. Resv. to your location.
I know very little about Brinks rolls, others can speak to that, but I assume they're rolled by specific "Brinks" facilities and outlets.

There is evidence that some 1971-D and 1977-D half dollars were struck on silver planchets....and with the other stuff floating around that all of us have been finding, it is very feasible that there may be something nice like that floating around in bankrolls. Keep your eyes peeled. Sooner or later one of us may get very lucky.

What does NIFC mean?

Eagle, When I read your initial post about the 77 Kennedy half I was thinking, commemorative issue. But then I though more about it and checked the US Mint's site under historians corner, and there were no comm.s struck that year.

Now that I see your pics, I'm not sure what to think. Odd, yes. Rare, not sure never heard of that type of coin before. Novilty coin? Eh!

I will say this, it is unique.

I've found one similar to this. I posted a picture a while back. Same thing with the edge. I think it was chromed.

I do not think it looks like mercury. I think chrome plating is more likely than silver. I would keep it because it is an interesting conversation piece.

My bad Duke. I should have posted the answer when I found out what it meant.
