I found a 2007P Rooselvet Dime in curculation the other day, without the reeded edge. The coin is the same size and weight as a regular dime, only with the reed edging. Can anyone tell me what causes this and identify the error for me. Thanks
From what i understand, coins that are missing reeds are not errors but smoothen out by slots, or wending machines. If the coloar is missing therefor the reed it would have been broadstruck. Siggi
I might agree however; this coin has no evidence at all of ever having a reed edge. slot machines or vending machines would not destory all the reed edge in such a short amount of time. the coin is only 4 years old. Furthermore there is no tool marks to indicate that someone removed the reed edge. the edge of the coin looks as smooth as a penny.
I do not know how long the slot or wending machines take to smooth out the reeds. But if the coin is the same planchet size and it´s just missing the reeds then it´s a post mint damage. Ergo slot or wending machines. I have seen many posts even here on the subject and they have smooth edges as yours. If the collor was missing when it was struck is would have been broadstruck as the metal is free to flow. Siggi
QM, It doesn't have to be caused by a slot machine or a vending machine. Here's a chance for you to try it for yourself. Using another dime, hold it between your thumb and forefinger and tap it against a smooth slab of hardened steel. Keep rotating the dime as you tap it on the steel. See how long it takes you to wear away the reeded edge. My opinion......PMD! Chris
When you stack the smooth edged coin between two recent date dimes, does the dime appear slightly lower than the other two dimes? Extensive vending or slot machine use will broaden the edge of the coin but not usually change its weight. As I recall, the reeding is imparted when the blank planchet is in the die collar and the moving front die strikes the blank forcing the metal of the blank to flow into the contours of the two dies and the reeded edge of the die collar. A broadstrike will occur if the die collar is too big for the coin. The coin you show does not appear to be a broadstrike. Often coins in a casino or laundry environment are constantly recirculated through change machines, thus, they receive a high amount of use in a very short time.:smile
I see traces of the reeding, especially in the third picture. Slot machines or vending machine might need longer than that, but get it stuck in a commercial dryer and you can probably lose the reeds in just a matter of a few days or less. A dime may now weigh much so as the dryer tumbles it the hits on the edge are rather light, but if the dryer is used even just once per day in a month that would be 18,000 light hits on the edge. If it averages one use per hour that's 432,000 light hits on the edge in one month. This is assuming the drum takes 2 seconds to make a rotation. If it does one rotation per second then it's 864,000 light hits on the edge.
