    state quarter error ?

    my scale is sensitive sensitive to 1/2 milligram - i'll weigh it out of curiosity's sake. You're right about the Denver and Philly mint. When I was on the east coast i could find die cracks on state quarters all the time. I haven't found a single one out here on a D quarter. One one hand, the Denver mint makes beautiful coins, but on the other hand, if we didn't have the Philly mint we might not have all these awesome errors we see

    state quarter error ?

    Thanks for the input. That really sucks that someone would plate a perfectly good state quarter. I see them sold for insane amounts on late night infomercials though. Maybe some kid really wanted a gumball or something. Come to think of it, this is the first 'P' mintmark state quarter I've ever found here in Denver -- you can imagine that we are inundated with 'D' mintmarks. I think that kind of supports the 'silver' or 'platinum' plated theory. I'll weigh it tomorrow and verify that it is weighs slightly more than the standard weight for quarters.
  3. I hate those topics that have a question mark after the word 'error', but I can't help myself here. I just found a Mississippi quarter (P mintmark) in a roll of quarters from my bank (not an uncirculated roll). It stood out rather quickly; it has no copper color on the rim. The rim is 100% silver in color, so much so that I was certain it was a pre 1965 quarter. Otherwise, it looks perfectly normal. Any ideas? Not sure how relevant it is but I'll weigh it in my lab in the morning to get the exact weight to see if it is off at all.
  4. is this a true mint error? the '1' in the date is missing, and that looks like a grease die error. what the heck happened to the 8 or 9 though? It is definetly an 8 or 9 because there in a nice S mintmark on the reverse of the coin. the reverse of the coin has no marks on it (i.e. completely normal), as does the rest of the obverse. let me know what you think.
  5. It's broadstruck. The diameter is a little bigger than another Indian cent I'm comparing it too. It's also a little thinner, although I'm not sure this observation is pertinent. thanks.
  6. Fair enough, it could be broadstruck, slightly off center, or have misaligned dies (MAD). How does one tell the difference between these errors? thanks in advance.

    Rotated Die Question

    I read somewhere that the US mint considers less than a 5 degree rotation permissible. Serious collectors of rotated dies (like included) don't collect anything with less than a 90 degree rotation - with the possible exception of some of the coins where die rotations are realllly rare (franklin halves, morgan dollars, etc), and even then the cutoff is anything that is blatently obvious (like at least 45 degrees). Also take into account the rarity of a roation on a given denomination/year/mint mark. This site (it is not mine) has an inventory of known rotated coins http://www.geocities.com/RodeoDrive/9830/. It only lists coins rotated from 90 to 180 degrees, but you can still get an idea of how rare a rotation is by looking at their list. Cool find though! I've never found a rotated coin in circulation, and I look for them every day.
  8. http://www.geocities.com/robbudo/1875offcenter.JPG This one has been in my collection for awhile. Is it off center a little bit or broadstruck - and how do you tell the difference? Thanks!

    Indian Cent Errors

    Here is a link to my flying eagle and indian cent errors. They include rotated, off center, broadstruck, misaligned dies, laminations, off metal, cuds, die breaks, and strike thrus. Enjoy. www.geocities.com/robbudo/indian.html
