Hi all, although this is technically a variety and not an error, I could not find a "variety" sub-forum so I will post it here. Here is a 1951-D triple repunched mintmark, listed as: 1951D-1MM-008 (coppercoins) RPM-008 (CONECA) WRPM-008 (Wexler) I will post some more varieties later this week. Most of them will be Lincoln Cents, which I specialize in. Yours truly Sweet Simon
Great find, and I also look forward to seeing more varieties. What method/camera did you use to get that kind of a close up?
I have a Nasco binocular scope, and use that with a combination of built-in lighting and an external lamp. Then I simply shoot a photo through the eyepiece. The camera I use is a normal hand-held digital camera. The first RPM photo was taken at 30X, second one at 20X. I included a pic of my desk/setup. P.S. good to see someone else from the Bay Area! :thumb:
That's a pretty neat setup. Does the scope come built with the internal lighting or did you have to install that yourself? And it's great to see another bay area coin guy, there's more fellas on here from northern cali.
The scope came with internal lighting. Technically it's a scope designed for use in a science classroom, but it works fine for coins. Sure beats taking a picture through a loupe, which I did up until a few months ago. I couldn't get close enough to the parts I wanted to photograph, and the angles were impossible. I would highly recommend anyone who is currently using a loupe and is unsatisfied with the detail they can see from simply searching or trying to take pictures, to save up and get a scope. You will notice your quality of searching will increase greatly.
I just got my microscope/camera unit about 2 weeks ago. Even though it is a cheap set up, it makes a big difference.
Nice set up to study errors. I cant believe you take pictures through the lens though. Never even thought of that. Im beginning to hate taking pictures of errors.
I mostly collect varieties (doubled dies, repuched mintmarks, etc), because they require close-up photographs. Errors, which can affect the whole coin, don't really benefit from closeup pictures. I have a lot of trouble doing whole-coin shots, because I can't get a picture of the whole coin under the scope.
I found a Kennedy with a double D mint mark just a hair off the first barely notice but It caught my eye for a second look, How do you know if its a rpm or just machine doubling?
Use a good loupe and look at it up close at a lot of different angles. Look for split seriffs, rounded edges. If it is MD, the metal will look like it was squeezed out from under the MM and be flat. Go to one of the error / variety websites and see if you can match the RPM.
I use a stereomicroscope, too. It came with a gooseneck camera that slips over one of the eyepieces and connects to the computer via a USB port. It isn't a triple, but this is my favorite RPM.....a 1936-D Buff. Chris
