Bank etiquette when you want to weigh bag of coins on site?

[JerrySpringer]

I think I was burned once on a bag of quarters at a bank, being shorted maybe $40. Decided after that I should just buy boxes and not bags as the worst they could be is short a few quarters. Same with dimes. Less hassle to worry about being shorted in boxes. But lately when I go the bank that sells me bags of cents and nickels, the generally have a bag of quarters or dimes on hand. The higher price per each bag, $1000 each I believe, is a little high some weeks for my budget so I have been non-inclined to even entertain the thought of buying them. But I am thinking now if I can weigh the bags to make sure they are with a few ounces of what the weight should be, I'd probably OK with not being shorted much if at all. Believe me, the only convenience of the bagged dimes or quarters is I can go through them in no time instead of having to peel back the paper fed rolls ones. Whether the chance of silver is better in a bag because there may a hot streak of a widow's dump in them, well that is edge that appeals mostly.

So, what is a good method of asking the bank if I can weigh the coin bags without them getting weirded out by the request?

Best method is to not do it. I've been shorted, as I'm sure most here have. Just inform them that their machine might be off. Make the least amount of waves as possible.

The bank's counters are up and down. I figure the margin of error is less than consistently paying 3-13% on Coin Star.
