Actually I am not, and did alright in medical school. There are indeed sebaceous glands irregularly spaced in the finger tips. So, no, I am not...
Actually there ARE sebaceous glands on fingers, and fats/fatty acids are in the residual of a fingerprint (as well as salts and amino acids and of...
I'm not sure if that is correct as the explanation has been that the oils are acted on by bacteria and generate organic acids that etch the coin....
Possibly a better choice I use is ammonia 1:1 with water and tamp with Q-tip then rinse with mild soap and water thoroughly. Acetone will only...
Yes
We appreciate your sharing, regardless of small details. I know even the best of us mess up a little now and then. Keep it up, love your apparent...
Hey, that's right, forgot to mention that it was gold and bought a few years ago for slightly BELOW bullion. Simple design but very effective!
Piefort 1979 One Franc: [ATTACH] [ATTACH] This was shot through the original mint plastic; cheaper than the 2 or 5Fr. but IMO in hand the...
Here is one last one - this is a 1964 threepence struck on a CuNi ROUND blank, but into a dodecagonal die and collar & thus somewhat analogous to...
Here is the 1963 Half crown struck on penny blank (I apologise for the photo quality as shot through the NGC perspex):[ATTACH][ATTACH] Photos do...
[ATTACH] OK, here goes 1975 10 pence:[ATTACH][ATTACH][ATTACH] Note that this 10P was struck on a bronze blank, the second from top picture is...
I assume you are in agreement then with what I said? This specimen is near round it appears. My OMS coins, and I have quite a few are much more...
Further comment: I agree the shape is off for a 20P and more consistent with a small flans slightly pushed into the multi-angular shape. Also,...
Absolutely beautiful design that I NEVER get tired of. Compare the handling of Balboa to the US presidents on the "golden" presidential dollars!...
I agree to that; for the record: 3.56 gm for the 1982 penny blank; 5.0 gm for the 20p. Other foreign could substitute as well. I still say...
Does not the lustre in the device recesses bother you? IMO the slight silvery look is sheen or min lustre across the surfaces and no corrosive...
Paddy - do you see what I mean about the difference in what you showed versus the OP coin? These appear at least to me quite different. And thanks...
Yes a series would be nice. Careful with any scratching please. I only say what I say as I have more than a little experience with 20th C OMS.
Uh that would NOT be a blanket offer! LOL As stated above there should not be lustre in the device recesses in an “environmental”.
IMO that coin needs to be weighed and seen in hand as similar OMS are known. Brit OMS do not bring big prices but if genuine might go at 100 USD...
