A Difference In Thickness?

The coating on the zinc is just about as thin as it can be and still cover the core.

Again, coin thickness varies from year to year based on striking characteristics. This can vary dramatically from year to year. There is even a little variation within a year and in the last few years there has been some variation between mints.

The only significant change in recent times was a 1% reduction in strip thickness for 1999 and later quarters. This was within tolerance for weigh and they might have puched the blank slightly larger to compensate for the weight discrepancy though this information is not yet available.

I've noticed since 1982 with the 'zinc ' introduction thinner cents.it interested me, because after re-rolling searched rolls i'd have to add a cent to get the count right ,;according to the a hand held; roll coin counter I was using,. well after some double and triple checking it was and is indeed to the stack height difference.which is how the counter works "stack height "a roll of post '82 uncirulated cents will be shorter than say a roll from '81. by one cents thickness in a 50 'stack' count stack.now some math;say, I've searched approximately 600,000 (post 1982)thousand cents divide by 50 (per roll)12,000 rolls. at one cent per roll loss it would have cost me $120.00 .. P.S. i'am glad I noticed cause using a hand held counter allows me to easily /and speedily re-roll empty (rolls).just have better things to do than give the bank "more" of my money.when I un-roll coins, I do so carefully; as not to tear the 'bank rolls' so I can reuse them.

I'm a rather pesimist when it comes to our government release of statistics. That being said I highly doubt that there is a great quality control at our Mint varifying the thickness and composition of the matalic sheets they make our coins from. You must remember they do not make the metalic sheets, they buy them and any organization that is famous for paying hundreds of dollars for a hammer just can't be trusted. I've weighed numerous brand new cents over the years with a few scales that are accurate to 0.001 Grams and have a problem aquiring that famous exact government released weight of 3.11 Grams per cent. I'm sure the thickness as well as the weight varies and they don't care. Even if you could prove that numerous cents are different from what they say, what are you going to do about it and they no there is nothing you can do. If the cents came out ten times normal size, the mint would just say your in need of glasses. Especially ones with Martinis in them.
