Pete2226 Pillar of the Community United States 3330 Posts	Posted 07/20/2015 12:28 pm One source I have identifies a rolled thin planchet as very rare. How thinly rolled must a planchet be in order to be collectible? Here is a 1994-D JFK Half Dollar (on the right) rolled thin compared to a normal 1994-D JFK Half. The normal is 2.15 mm thick which is as specified. The Rolled Thin is 2.0 mm thick. I know that the further off specification it is, the better. But how far off is considered to be enough to be collectible? Report this Post to the Staff

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 07/20/2015 12:39 pm Thickness of a coin at the rim is a function of strike pressure, stronger strike equals a thicker rim(compare a proof vs. business strike). A planchet is not truly thin unless it is underweight. Report this Post to the Staff

This coin is only underweight by 0.02 g - - and I do not call that underweight. I suppose that if it weighed 11.00 g or less (normal being 11.34 g) then that might be considered to be underweight. Still not sure where to draw the line on that, however. Interesting that I found a PCGS graded 1956 Lincoln Cent rolled thin and weighing 3.11 g. Seems like this TPG does not quite follow this rule - so I am still a little confused about how to think about this variety. That coin can be seen here: http://www.bgasc.com/product/1956-l.../error-coins Error-Ref shows a Rolled Thin Quarter which is 0.75 g underweight. It can be seen here: http://www.error-ref.com/rolled-thin-planchets/ Intuitively, it seems to me that being underweight ought to be a requirement for a definition of a rolled thin planchet - the more the better. It seems like how much underweight to be called a "rolled thin" may be a bit arbitrary. Thanks for your help! Report this Post to the Staff
Halo1st Pillar of the Community United States 2775 Posts	Posted 07/20/2015 1:22 pm Pete, I agree there is plenty of good info concerning cause and effect, but very little is recorded concerning rolled thin and split planchet stats. I to have searched in the past with little to none and or frustrating results. I believe the first example 1956 LWC must have been a typo or someone missed something else. Yours make the weight so low pressure maybe? Thanks, Doug. Report this Post to the Staff

Even that wouldn't be underweight Spec is 11.34 grams +/- .45 grams so a half dollar would have to weigh less than 10.89 grams to be considered underweight and out of spec.
