I always check my change whenever I get it back and I noticed the P on this Harpers Ferry quarter with the naked eye. When I got home I used my loop and took some pics and was wondering what your guys thoughts are on this quarter!
Looks like die deterioration to me but I wouldn't bet my life on it I'd wait for somebody else with a lot more experience
The spherical aberration makes it a stretch for even those who are accustomed to 2D magnified "inspections" to allow their mind to deconstruct and then reconstruct the image concluding it is most probably DDD. People whose eyes and minds are accustomed to much more realistic 3D magnified images simply reject such images as well as many other types that are typically below par. I believe the OP would really enjoy a quality loupe. Perhaps walk into your local B&M and they'll most likely let you test drive theirs for a side by side comparison. Or skip all that and get a stereoscope.
Looks more like a repunched mint mark.... though I thought that could no longer happen.....not saying that is what it is...just mentioning it...
But if it was a repunched mint mark it wouldn't have the deterioration on the backside of it would it the back side of the P in the one pic looks thick to me
I thought it was really interesting walking out of the store when I noticed it looked doubled so when I got home that’s when I used the loop. The last two pics with the pink background it just a regular camera pic.
http://doubleddie.com/2247758.html didn't find any listings for doubled mint mark for harpers ferry, but here is other things to look for
Here is where I believe your technique is hurting you. Not the best loupe in the world but not a bad one. Much more capable than you've managed. The trick is to center your camera lens on the imaginary line that we'll call the pupil exit. Square off and on that center line should eliminate all that distortion from being out of kilter. Brace your loupe holding hand and your cellphone too. Use voice control to snap the pix. Get an app if your camera won't do voice "shutter" control native. Also, if you set your camera to zoom in slightly, you'll find it easier to stay in the sweet spot and get a wider field away from the edges which distort even on the best glass. Here is one I just snapped with a cheap 7 buck knockoff of a hastings triplet. It is only decent, but, the difference between it and a 100 buck zeiss is huge. Big difference, huh? Just an old touchscreen phone (obsolete by a few years) and a cheap 10X triplet. I even used the camera flash...... just so you know. Not bad, huh? So try again???
This is a single squeeze die produced coin, and the mint mark was on the die, so it can not be a repunched mint mark in the traditional sense, so a single squeeze "skid mark" , SSSM, as the lettering close by is not doubled.
I don't think so. http://varietyvista.com/Watershead Dates.htm "1990 – The U.S. Mint began punching the mintmark into the master die for the cent and nickel denominations. The last year possible for an RPM on a business strike cent or nickel is 1989. There are several known RPMs for the 1989-D cent but the last known nickel RPM is dated 1984-D." Productive of the moderator to provide the OP no motivation to produce a decent image of his skidmark, well not really.
Bronson, the 4 images you gave of the mintmark in your first post #1 was more than sufficient to say it was not a repunched mintmark. Ordinary Fool seems to have a penchant for requesting everyone to produce an image that is "suitable" for him to be able to explain, so doing so or not is entirely up to you. That is his idea of being productive
It's year is enough to ascertain it isn't a RPM. I can see how not being able to utilize your equipment to the point rendering near abstract impressions is preferred to reasonable quality images, well at least here anyhow. Nobody collecting coins needs to give any attention to imaging their coins.
You are more than welcome to post your images also, so perhaps some will strive to emulate your enthusiasm for improving the photographic arts on the forum.
I wouldn't have any idea how to do that or even take a picture. See if you can determine from the stellar pix (I've seen better from a flip phone) of the 1964D GWQ which reverse it actually is.
