Agree.
A common occurance caused by vending machines or sometimes coin wrapping machines.
No extra value, still worth 50 cents

When you say un-used, I think you mean Mint State or uncirculated which is the proper terminology. Also as stated, your coin has been both cleaned and circulated so there is not too much value over bullion. There are just too many of them out there in uncirculated condition. At one time I had 9 but ...

What you have is the EAX Crow -Bouey signature worth $10-15.00.
It is the EAX Lawson -Bouey signature that is more valuable.

Looks like a Die Chip. Errors and varieties are not uncommon on 2001 dimes.

That is the way the sheets are printed. The next sheet would all end in 36 and so on so that when the bills are cut, you would have 40 bundles all in sequence.

Can't really grade without a picture. Value would depend on condition as well as the signatures and prefix
which you did not provide. Being off centre and worn would certainly affect the value.

thanks again. can i send you a few more items

You can post as many as you like. Just make sure to avoid confusion, that you have a separate post for each item

It depends on what coins you got graded. They all have their own grading standards although NGC is considered one of the big three when it comes to grading.

Those are pretty common even in uncirculated condition as there was over One Billion printed in that series alone
Because yours are uncirculated and in sleeves, you might get two dollars each if you can find buyer.

Those are pretty common even in uncirculated condition as there was close to Two Billion printed.

I somewhat agree with GBELEC bit I think he may be a little high on his values. In my opinion because of the condition, the shinplaster might be worth 8 or 9 dollars at the most. The 1973 Dollars, because there were Billions produced are not hard to find in uncirculated condition are probable worth ...

It's not just the writing, the bill has been folded twice creating three fold lines. If this was in uncirculated condition, it would be worth five figures.

It can't be rust showing. Those cores are made of brass plated aluminum bronze, neither of which can rust.
It just must be the chemical reaction.

It shouldn't hurt the collector value of the currency and they can always be returned to the bank for face value, it is just that they are no longer legal tender.
