Such a coin would have to be seen to determine its value. I suggest you take it to a coin shop and ask them to look at it for you.
First weigh it it should be 2.5 grams if not some one could have milled out one side. but with out seeing the coin it's hard to give an opinion. Take it to a coin dealer or show let them look at it.
It is your control. Your baseline reading.
Chances are it is worth something. The question though is, was it a nickel struck on a quarter blank? Or was the nickel simply struck off-center? If it was struck on a quarter blank, the edge will have both redish brown and white. If it was struck on a nickel blank it will be a solid color. The best thing to do is take it in to several coin shops and get different opinions on what its worth. It is hard to give values for error coins sight unseen. But some coin dealers specialize in errors while others use them simply for curiosities.

so in other word you need to put it into a number model, 91 is 65percent of ( times) blank....... 65percent * blank = 91 . So you have to divide 65 by 91 and u round that number . so the answer is 140
A 1984 nickel with one side stamped with Jefferson and the other side blank is likely a novelty coin created after minting. It does not hold any numismatic value to collectors and is worth face value, which is 5 cents.
Your off-center error cent will be worth $2 to $10, depending on how much off-center it is and how nice of condition it's in.
The value of a quarter with one side stamped heads and the other side blank would be 25 cents in terms of its monetary value in the United States. The design on the coin does not affect its face value or purchasing power. This type of coin may have been altered or misprinted, but as long as it is recognized as legal tender, it can be used for transactions at its full 25-cent value.
This type of error of misstruck coins is called 'Brockage'. A Lincoln penny with this error is valued at $35.00
it is in the blank right next to the other blank blank
It depends, sometimes they are called blanks, other times they are called planchets, occasionally you will hear them called flans. All of them are correct though the term planchet or flan is used more with coin collectors while the term blank is used by pretty much everyone else.
There shouldn't be any other dates stamped on your half dollar. Only the date 1969.

No, I have never seen a 1943 Florin stamped into a bottle cap, but I have seen plenty of other coins stamped into bottle caps.
