It would probably fetch more than melt on ebay unopened... but then most silver goes for more than melt there. How old are you? Maybe you could put it in the back corner of your safe/SDB and forget about it until 2065...
To me, it seems like it would be hard to tell if that had already been opened at one time or not. I'd be suspicious of the contents. It might be possible to weigh it in the wrapper and add a few grams to see if the weights match up with what 20 90% silver halves should weigh. Or, maybe you bought them from someone you trust and this is all irrelevant...
I must respectfully disagree as that is not an original sealed roll. I've little doubt the OP could carefully unroll the shown end, search the coins, are replace with the proper ends without any harm being done. While chances are there is nothing special inside, who knows for sure. Its worth a shot IIRC.
+1 the end (shown in 1st pic) looks like it's been opened before. It's not crimped the way it should be. If you do not know the person you bought them from you really should check the contents. (lol, sometimes 'knowing the person' means you know you have to check to see what things really are.)
Sell as a BU roll. Honesty is best, so letting people know in the description that they are all BU '65s and that you checked to be sure the outer label is accurate may improve the outcome. Or keep them till silver rises. Whatever floats your boat!
Does not appear to be a bank roll either, even considering the fact that in those days, rolls were often put together by hand (at least at some smaller banks). If it were, it should have some sort of stamp identifying the bank. Not that this would mean much though.. unless you were familiar with that bank's rolls. Anyways, the roll looks to be nothing more than one put together by a person or dealer, and the label looks to have been typed on a typewriter. Possibly old inventory liquidated when silver values started going up a few years back... a lot of such rolls came out of the woodwork at that time. OP, If you popped it open, did you search for any very high grade pieces and/or varieties? IIRC, anything pulling a 66 could be worth more than the entire roll (melt value) if these are 65 business strikes (not SMS).
1. Has been opened. Open it again. 2. Put a Franklin on the end. 3. Sell on ebay as "unsearched half dollar roll" 4. Profit.
I'm quite familiar with bank rolls from the late 60s. My grandmother owned a small town restaurant and would often send me across the street to the bank for rolled change. The rolls would either be rubber stamped with the bank's name and phone number on it, if the bank tellers rolled the coins, or would have a person's name hand written on the roll, if a customer rolled the coins and brought them in to exchange for greenbacks.
