weighing your rolls

[alaskanfever]

how many people do this? And do you open all the rolls anyway or just the ones that weigh in at a heavier weight?

never even thought of this... may be a way to do it with limited time and TONS of rolls to search haha

I feel like with that many coins, there is to much possible varience that might hide one or two. Just my opinion.

My daughter and I have been weighing them for a few months. We still open them all, but it's fun to see how the heavier ones do compared to lighter ones. Although, let me warn you that we have gotten one 40% out of a roll that weighed in lighter... Generally, if a roll is quite a bit heavier, it will have some silver. No way I could ever not open them all. Nothing is 100% foolproof but date checking every coin. Even edge checking misses a few...

I weigh every roll, but I also open every roll. For those that are thinking of not opening the lighter rolls, think about this. My data shows me that:

238+/- means there are 21 coins in hte roll
226 grams and higher "usually" have a 90% half inside.
225.3 to 225.9 "may" contain a 40% half
225.2 and lower is "usually" all clad
213+/- means there are only 19 coins in the roll

Knowing that info, I got to a roll that weighed 224.6 (very light), and it contained a 1964 and a 1968. The reason for this was that there was a 1911 large British penny in the roll where a half should have been, and that odd coin only weighs 9.3 grams instead of 11.2 grams like a clad half would weigh.

Cards is on they money, looks like non stop with his #'s. I also weigh them out for the top picks for the time I have. The S mint coins lurk in there from time to time on the light to medium rolls. You also will get a steel coin in there that peaks the scale. Skunk. Crack open them all. Keep up the hunt.

Really bad idea considering some rolls have more than 20 and some less than 20 coins. Not to mention foreign, commemorative, and others have different weights making your guesses just that. Its called roll hunting for a reason. Although a forum called Coin Roll Weighing might be entertaining.

being an engineer I also developed my own weight spreadsheet. Its basically the same as CnC listed. These coins will generally have 0.5% - 2.0% loss of mass of over time through circulation. From my experience you can always tell when theres a 90% in the roll , but it falls apart with the 40%s because the weights are as follows

90% = 12.5 g
40% = 11.5 g
junk = 11.34 g

also if you are weighing your rolls make sure you open 1 roll and tae your scale for the paper weight of the roll , it usually comes in around 0.91 grams.

But what happens if your are 1 short and also have a 90%...I think weighing them is really taking a chance of maybe missing something good..I mean I can go thru a box on my lunch hour with no problems
