May Have The Greatest Beginners Luck With This Box Of Quarter Rolls

If I had them, I'd stash and save them all.... who knows what the future might hold

. What I would do is keep one or two rolls where they show heads on one end and tails on the other end unopened and search the rest for errors,varieties and high grade ones.

If, and I say if 47 rolls are all new enders but 3 rolls are not, I'd come to the conclusion that either they mixed in some circulated with the new coin in all the rolls, OR the box was opened and the bank stuck in 3 older rolls to make it 50 rolls.

I've gotten new boxes and found 3-4 circulated coins per roll, none as enders, and it just had to be left over circulated kept in the mix with new coin when it got rolled up. the box looked all new but upon opening the rolls there was a dirty edge here or there and older dates.

Id start by searching the 3 rolls that show the circulated enders, if they are 2021 heavy, then it's likely the entire box is contaminated with circulated coin and you'd be best off sorting it for errors and set aside one or two rolls of the best examples, than to leave them as mixed rolls, or try to sell them as new rolls of 2021 and the persons that buys it hits you with "there's circulated in here!"

if the box wasn't sealed still when you got it or resealed, it's very likely the bank just tossed in 3 circulated rolls to make it 50 rolls again.

Now as far as 39, 8, and 3, the washington crossing obverse is different than the State or Park quarters, you should have no issue telling it from any other quarter in the last 20 years including 2021 tuskegee, it will have the date on the front at the bottom below the bust. so if those 8 say 2021 on the obverse, it's also washington crossings, it's the only thing it could be.

still those 3 randoms give me pause, I've seen circulated mixed in with new in sealed boxes, it happens, and if it did here, you really don't want the older coins and contaminants being stored with the fresh new coins side by side long term.
So I'd start the investigation on the box itself, was it opened before you got it? Was it resealed? then the wrappers, is it possible someone searched it, stuck in some other coins to make up the ones they kept and then turned in the box?, then check those 3 rolls if the first steps don't come to a conclusion, then those 8 rolls if checking those 3 doesn't give you a conclusion of what's likely to be last 39 rolls from the evidence as a whole. maybe someone got the box with intent to keep it, didn't want to tie up $500 and just took 3 rolls replace it with 3 mixed rolls and turned it back in to the bank.

I won't tell you to open everything necessarily, but you shouldn't, let say, sell them as new rolls of 2021, and get complaints people are finding older coin in them.
I don't think you would want to put up $500 in new quarters for a rainy day just to find out 10 years from now, 1-5-10% of the box was circulated and been in contact with your coins in the rolls for 10 years either.
Generally I open the rolls and search for errors, and set aside the best roll or two of a new box into coin tubes and return the rest, so I'm not sitting on $500 in quarters forever. I'd rather use the money to search more then tie it up. But I understand some people make a couple bucks off of selling rolls on ebay and stuff. to each their own.

Now there's a chance for some high grade W mint marks!

The 2021s are quite pretty! I pulled a few very nice looking examples recently.

I also got a box 100 percent full f Tuskegee Airmen Quarters at my bank. I will just stash them.
