I was lucky the last two weeks i got in two bags that were back in 1993 so they have been sitting awhile. as for numbers it was a franklin reunion and was able to get 2 solid rolls of 90%ers and 34 40%ers. went in to pick up my order today hoping for more but the bank never got them in they said their supplier was out again.
Those clowns don't pay much attention to their date stamps.
I've had many "back to the future boxes" stamped months and years ahead as well as a vintage 1902 box once.
Good luck.
At a tiny local branch of mine they've been feeding me citizens dime boxes one per week that always have a date stamp from 2008 or 2007. I think it's the correct date stamp as I've been finding coins no newer than 2007 and no 2008 at all
They were both skunks!! Ouch!! Previously found 2 dream boxes with the same date...50 keepers in one box....80 in the other!! Oh well, maybe next week!
