I had some today that were mark, 1977, 1979( 1/2 )....1971, 1978 ( 3 ). Others were marked too, not the first time I've had them, won't be the last time.
ive gotten cwr cent and dime rolls labeled: "1990x45 1999x5" "2004x10 2005x30 2008x10" and other weird stuff like that, but it was from one bank and deposited by one person. I don't know why people would do that either. I have yet to come across a roll with silver years written on It though.
Anytime anything is written on a roll it's a good sign. Date rolls are great because someone collected them, and then someone dumped the collection. Not always silvers, but always a good sign. Found a couple of date sorted rolls in dimes this week, my first ever. No silver but still very cool.
I got some rolls the other day that were dated. They said "1971 silver-copper" and said the same thing for '72, '73, and '74. No silver was found, but someone was misinformed, haha
