I bought two 50 cent rolls online once with silver enders. I bought them because I wanted the coin that the silver end was, and that bonus factor of possibly more was neat

I bought them for around 32 a roll. First thing I did was weigh them..... of course to check and see if one weighed more than the other. It did. I dont remember the exact number, but one was like 345 and the other was flighering between 345.5-346. The one was weighed more had an additional 40%er in the roll. I immediately realized the people selling them would of course weigh a roll before selling! If it weighed more they would keep it.... but if they were just the ends or possibly 1-2 more (to keep people coming back) they sell it for more. Tricky!
