The fact is, silver coins develop a toning over time unless they are in a vacuum sealed holder. That stapled thing is not even close. The ONLY way a nearly uncirculated coin, in that container, could be THAT shiny is for it to be cleaned.
I spent several years assembling a set of untoned uncirculated Franklin halves. There are lots of untoned examples, it all depends on how they have been stored.
Maybei they took it out of a unfinished proof set and put it in there for a better looks because no one wants to buy a case with just a Ben Franklin half dollar.
I got whole rolls of Franklins.. You can take them to the pawn shop get $5 to $7 each for them. Or put them on E-Bay and you may get $10-$60 for them. I have sold countless Franklins on E-bay and normally get $10-$20 but sometimes you can get up to $60 for one. Good luck
