Anything is possible with a coin, but could this dime be struck on a wrong planchet? Standard weight should be 2.27g and seems too high out of weight tolerance...thoughts? Thank you much!
It's a higher weight but not a lot. Probably just a Planchet that was rolled thick when the sheet was created. Normal issue. It wouldn't be on a wrong Planchet.
One other question...are dimes notorious for being out of tolerance from true mint weight? Of all denominations, dimes seem to be the most inconsistent
Expected weight/tolerance = 2.268 g +/- 0.091 g Agree that it may be a Rolled thick planchet, although the definition of such is not precise. In my view, if the thickness exceeds tolerance, then it can be defined as rolled thick. Suggest measuring at 4 places around the circumference with calipers to 2 decimals in mm. Another possibility is a tapered planchet. Expected Thickness = 1.35mm with tolerance: -0.076mm/+0.127mm.
In general, does a coin from a planchet that is rolled thick have any kind of additional value? Or is it a spender (if not a key date)? Thanks
I recently found a zinc cent that was 2.7g. Slightly thicker rolled planchet. The thicker the better in terms of value. If it is slightly heavier and thicker than the tolerance range, there wouldn't be any or very little value. But if it is much heavier and thicker above the top end of the range, then it has value. Paddyman would know.
Marginally, slightly over the tolerance weight, but so little that it would have no premium as such, imo .
I don't feel a thick or thin planchet coin really has any premium until it is .3 to .4 grams outside the tolerance range. This dime is only .07 grams out of tolerance.
Thank you all! I’ve been learning quite a bit since joining CT and I just want to thank you again for being patient with all of my newbie questions.
