There are different types of doubling, some worthless, some with a bit of premium.
What type do you have?

Please explain what you think is an error.
It just looks like a well worn 1922 nickel.
I would grade it at VG-8

Not an error, it is damage. No premium for damage

Welcome to Coins and Canada
Looks like you have a rare note there. I found this on another Forum.
Of course condition would play a big part in its value.

According to Charlton's it's 100 times rarer than a regular 7 digit radar
"and pricing should be arranged between buyer and seller".

Neither one is in the best of shape.
Might be worth 50 - 60 cents each.

If you do, make sure you post it under the Tokens, Medals Forum as it is not a coin.

Someone is selling a picture of a 50 cent piece and
the bididiots think it is a real coin.

Why are you showing the Reverse?
It is the beads on the Obverse that you count.

Sorry but that looks like a Small Bead to me.

That is a common prefix and in that condition, it would be a hard sell at $2.00.

Welcome to Coins and Canada Instead of showing 5 pictures of the reverse, it would help to show at least one of the obverse. There might be something on there that would make it “rare”. From what I can see from the reverse, you have a regular 1952 nickel that has been Struck Through Grease, a minor ...

I'm not sure if anyone here can help you but if you go the Coin Community Forum, they have a section
dedicated to "US Paper Money and Banknotes." List your photos there and I'm sure that someone will help you.
They have a couple of knowlegable members on early notes.

Not a weak strike.
A weak strike would have smooth fields.
It has been etched.

Welcome to Coins and Canada.
It is one of two things, that is a third party packaging so they either plated the coins gold
or they have toned. What does the other side look like.
In either case they did not leave the mint looking like that so technically it is damage.

You didn't provide year or signature but I think I found it.
Is it the 1986 bird series with the Bonin -Thiessen signature?
If it is , it is worth $2.00 circulated and $4.00 uncirculated.
A very common bill
