Mercury diagnostics

Does anyone have a pic or can recommend a site that would show the diagnostics for a 21 and 21d Mercury. I would
like to learn what to watch out for to avoid counterfits, altered versions of this coin. I'm not a slabbie so I need to
rely on my own knowledge which isn't all it should be yet.

    I can hear the rumbblings of the forum gathering up the info for you right now.
    Wont be long now.........

    Sorry I forget the member that showed us that altered `21,asking for a grade opinion.

    He didnt say anything about it being altered and a bunch of us,me included,totally missed it.

    Still trying to get the egg off my face on that one.......and the other one....I dont wanna talk about it.image

    Oh ,His fake `21 had a closed-9 as apposed to the real 9 which is open.
    Also the 2 in 1921 is different that any othr 2 on a Merc.

    Well, I don't have a picture but there are several books that show you what to look for. The PCGS coin grading book has a nice picture of the real 1921 dime. Bill Fivaz' counterfeit guide book also has a nice picture of the 1921. The 2 has a slight upward curve to the base. The 9 is on open 9. On later dates it is a closed 9.

    I'll do better than that, since you're going to the Port Richey show on Saturday, I will be there and I'll
    bring with me a couple of slabbed ones and I'll give you a brief tutorial.

    I do not have the picture any longer. It was a 1941 that was altered to a 1921. Beside the mentioned obverse date problems the reverse was the type seen from 1926 untill the end of the series. It was a dead give away that the coin was altered also.

    Wow, they actually counterfeited a 41 to a 21.

  • Thanks everyone, I have some info to start. Brian, I'm looking forward to the show and your tutorial. You can't learn
    enough in this hobby. I've looked high and low for the PCGS book but it is out of print so I guess I'll be hunting ebay
    to try to find a copy. I'll look for the other book mentioned.
