A friend of mine showed me this 1964-D Washington quarter and asked me if it was a DD. I told him I would post some pics on the forum's board and get your feedback. I would also like for you to tell me whats up with the MM. Is it an RPD?   |

Good clear pictures, but need larger pictures to make a determination. This shows promise though.

The size of my photos are restricted by the 100k restriction but I have cropped the images a little closer in order to post larger pictures. Thanks,   |

Yes, but you're only at 38K! :D
Is there any way you can zoom into the 'O' of the word 'OF'?

Jim I am using a macro setting. Its actually the super macro on my canon s2is.
Vaslin,
I am using photoshop to resize my pictures. I guess 100k in photo shop is not the same as on this website. Let me do some more resizing and see if that gives you enough detail.
Thanks

Hi, Mechanical Doubling....no die doubling. It is actually easy to tell even on the smaller pictures. A larger pcture of the mintmark would be needed though. Thanks, Bill |

Here are some close-ups of the MM. Thanks for the opinions on the doubling. That was my opinion as well.   |

It's Machine Doubling - not " Mechanical Doubling" - there is no such numismatic term. Also an RPD is a repunched date. Only happens on 19th century coin series. What you're asking about would be RPM, repunched mintmark - and no, that's Machine Doubling too. |

Thanks CC. Yeah, I always get confused and used machine and mechanical interchangably.

Is there an "easy" way to tell the difference between RPM & Machine Doubling? |

The best way is to own one! :D As obvious as that sounds, once you actually hold one in your hand, the Machine Doubling ones become easy to spot. Machine Doubling is flat with no definition of it's own. Real doubling has it's own ridge structure, height and character. Most RPM are nothing more than just 'split serifs' where you can see two serif points. |

I would respond, but Vaslin said it as well as anyone could. If you buy a few real RPMs the difference is easy to spot.
