As Bill stated
Post mint damage.
It was done after it left the mint.

I agree.
Not a diecap but PMD.

Sorry meant OT4
Hit the 5 buy mistake.

OT5

It doesn't reall y matter how it was done. There are a lot enterprising people out
there that do many strange things to coins.
The main thing is that, as shylo stated and I agree, it couldn't have been done at
the Mint so that makes the coin PMD.

I take it that all the coins are nickel coloured and that is lighting
that causes two of them to look gold?
Also, what is the significance of the third coin on the picture of the Obverses.
It looks too be the same size as the centre coin.
Just trying to eliminate possibilities.

Thanks

There is one listed on eBay from Gatewest Coins for $27.00
Their prices are usually pretty fair.

A wrong planchet was my first thought too but then I realised the OP said that it was larger than a regular Nickel. This eliminates a wrong planchet because it would have to be smaller or same size as a regular size Nickel planchet or it would not fit in the collar. Guess we will have to wait for ph...

We will have to see full pictures of obverse and reverse to be of any help. If you can take a picture beside a regular nickel, that would be great. It could be anything but I'm fairly certain it didn't leave the mint that way. A nickel is not too much smaller than a quarter to start with, so it can'...

With the condition those bills are in,
I don't see anything worth more than face value.
Maybe you can sell them to a LCS in Russia.

Hard to tell with the lighting but does look like it
might grade in the middle MS range.
Probably worth $2-$3.00

Hard to tell from those pictures but those probably grade
between VF30 and EF40. Your other coins may grade differently.

Also in 1967, some quarters were 80% Silver and some were 50% Silver.
In 1968, some were 50% Silver and some were pure Nickel.

Your prefix is a good one.
There where only 80,000 printed with *H/F.
Hard to tell condition from those pictures but could be
worth in the 100's if uncirculated.

For the third time NO!!

There is no way that could be plating from the mint. The planchets (blanks) that the mint strikes these coins from are plated before being struck. If by some small chance there was a bit of extra plating on the planchet, it would have been flattened with the pressure of the strike. The fact that wha...
