Still trudging thru my coin stash and came across a ‘91D and a ‘91P dime that I put aside for whatever reason. Well, I came back to them and weighed them, only to find that the ‘91D weighed more than 2.27 grams...it weighed 2.31 grams. The pic of the two edges, the ‘91D is on the left. Possible reasons for such a weight difference? Thank you.
Hi Imho, not all planchets are exactly the same weight. It doesn’t matter which mint they originated from. As long as it is within the allowable weight tolerance. In which case your coin is within the allowed weight tolerance. Yours are slightly lower but still within. The stated weight specs are 2.5g
Hi! Thanks for responding R_rabbit. I know I’ve seen a schedule of sorts, somewhere online, regarding allowed weight tolerances, but The Red Book says 2.268g/2.27g for dimes. Not trying to split hares just trying to comprehend with my tired brain. Is it to the tenths or hundredths of a gram, plus or minus, that is acceptable? . Again, thank you very much!
Are you trying to determine how much weight and thickness was lost due to circulation wear as the P obviously is worn more (looking on my phone)? As the coins are designed and manufactured to be recognized as currency and be accepted by vending machines with in certain tolerances. They are not designed as hallmark perfectionistic display only pieces.
How did you know that I’m a witch...?! lol. That pic took me back to the good ol’ days of all my childhood Saturday mornings!
I thought of that Bugs Bunny episode immediately upon seeing "splitting hares" I can't recall how many years .. nah ... decades ago that was ??
Thank you Condor101! That was the info I was looking for! Is it safe to assume that +/- .09g can be used for all other modern day coins?
Please note that even if your dime weighed a bit under, or over, those tolerance ranges, it would not be considered an error, or have any premium value.
No...was trying to figure out if the D was within weight tolerance and if so, what +/- variable is used. But thank you!
Well, I remember watching Saturday morning cartoons in the mid-70’s. So, using 1975 as the date it aired, that particular cartoon is 44 years old or 4+ decades. lol
No, each series/denomination has its own tolerance range. In the current coins the cent tolerance is +/- .1 gram, 5 cent is +/- .19 grams. dime is +/- .09 grams, quarter is +/- .227 grams, half dollar is +/- .454 grams and dollars is +/- .3 grams.
