late....so a dumb question

[captn cupcake]

so it's late sitting here listening to hair guitar on direct and surfing. I was thinking does a silver coin weigh more,less or the same as it's counterpart. because if there was a difference a guy could weigh a full roll of modern coins get a base weight,then a roll with just one silver and get a base then you could just weigh out the rolls without opening and rerolling unless there was a weight difference. back in late 80's we would o this with packs of baseball cards. the packs with special cards ie.. jersey, bat cards weighed more so you would buy that pack.

you can/could do this, but there just aren't that many 90% halves left in circulation comparatively and you would miss the 40%'s.

average coins have 0-2% weight wear from circulation.

clad half = 11.34 grams
40% half = 11.50 grams
90% half = 12.50 grams

in the old days when 40% halves were barely worth more than face this would probably be the way to go, but with silver anywhere above $20 per oz they are keepers and you can't find them consistently from weight checking.

wear on coins would make it tough to determine silver or no silver

naw blex you can always tell when the 90s are in them with a decent scale, the point is the 40%'s are to valuable now and you cannot reliably detect 1 in a roll of clad with a weight difference of .16g

Why not just scan the rolls with a decent metal detector. You should be able to pick out the higher conductive silver coins hidden inside!

Not that long ago, I had access to a handheld XRF machine. I'm wishing that I could get some time with that again. I'm certain I could scan unopened rolls of coin for silver. I'd go as far as to say that I might be able to "see" silver in unopened boxes. I have visions of scanning unopened boxes to weed out the skunks in a matter of seconds. Then, opening boxes known to have silver and finally narrowing it down to the roll before unrolling anything.

i guess but it only takes 10 minutes to flip a box of halves, either way you have to pick it up and dump it.

Not always. I have a dateless, worn thin, nearly completely smooth Walker weighing in at 11.1g.
