When I went through the quarter rolls I found some of the 1999 and 2000 quarter look unusual. There is a big bump on the reverse side and it doesn't like the strike cause it. Because the coins are fresh from roll, I'm pretty sure it's not PMD. Another fact is all coins have exactly bent, and I only found them in January (either 1999 or 2000) quarter roll. How mint made this kind of error coin? my guess is, the material for planchet was bent before cut. When the machine cut the planchet off, the rim was squeezed flat but the center has some bending left. The bending stay even after the striking. I hope someone can have better explanation. My another question is, is this be classified as a special error? I didn't find similar one on CoinsandCanada.  |

not sure what caused it but it sounds like they are concave a bit.. This could be caused from heat during the actual minting process.. some metals heat up more than others and if cooling faster than normal it might cause this... Is it an error ? I would say no but I am not a pro

I'd say if all the bends are exactly the same and they all came from a mint roll in January of 2 consecutive years then it must be a mint issue. If can you compare it with other quarters of the same year or month, then compare with say Dec. and Feb. same years, if different then you might have a some kind of a one time error. Just my untrained opinion.

Thanks pennyman. I went through other rolls in 1999 and 2000 but only found in January. I'll try to post it to CoinsAndCanada and see if they can treat it as a kind of error.

I cant see planchet material being bent for the same months 2 years in a row, But the obverse die could be used 2 years in a row, and or replica of.

I have brought this thread back from almost 5 years ago. I recently purchased one of these January 1999 25 cents with this interesting bend or bump. I discovered this thread while researching errors and varieties from this series of quarters. please note that it was hard to photograph but is actually quite visable in hand or even 5 feet away with light reflecting off of it. the first 2 pics showing the entire coin. note the scratched area on the obverse. that is a high point, the top of the bend or bump.   I had to use angled lighting to catch the effect of the bump. I took pic at 3 gradual angles to highlight it.       a couple of different light angles on the reverse which seems to be a larger ridge than the obverse.    would anyone like to wade in on this one? they didn't seem to get too far on it in 2013 when this thread was started. I purchased it about 6 months ago and hadn't gotten to it yet when I discovered this thread. who knows...I may have even purchased this coin from the author of this thread ( ebay purchase) comments please! thank you in advance.

Hello robmck1967. This variety has been noted on Pat Glassfords website: "Jan #7B - Second coin exhibits 'Tool Damage" the result of the Dies striking a Feed Finger, affects the left side of the coin. Warped fields on both Obverse and Reverse. Very early state with this damage. *Estimated value -$20.00" http://www.coinscan.com/mill/j00.html |

Actually Scissel, this one is the 1999 January example: http://www.coinscan.com/mill/j99.htmlJan #8 - "Tool Damage" the result of the Dies striking an object of similar or greater hardness. Affects the left side of the coin. Warped fields on both Obverse and Reverse.
