I noticed that feature in most of George V pre-1920 halfcrowns; and it was actually worring me why some showed this curved surface and other didn't.
Thanks bilnic.

Original weight of 20 kopeks (from Bitkin) is 3.60g 0.500 fineness and 22mm dia.I have exact same coin but is slabbed MS65 so I can not give you MS weight.I agree with majority on die wear.More wear to dies-more flat coin is so weight is lower than should be.

Thanks valdiman. Afer all your help I'm now pretty sure the Kopeks are good. I got them from a seller that I didn't trust too much, and bought just a few at a really low price to see if they were good; with the intention of buying many more, which I never did, since I doubted the authencity of the ones I received. What's worring me the most now is the Morgan dollar that is 0.2mm short in diameter.

Quote:Did you see my question about the Morgan dollar; could it be authentic and have a diametre 0.2mm shorter due to wear on the rim? It's a 1896 minted in Denver, and about a VF25 grade. No,unless the reeds on the edge are completely gone (Heavy slot machine use?). And the Denver mint did not strike Morgan dollars until 1921.

Sorry Conder101, you are absolutely right and I made a huge mistake. Since the coin has no mint mark, it's from the Philadelphia mint, and not Denver. I took some pictures to see if you could help me determing if the missing 0.2mm could be due to wear on the rim:   And here you can see that the diameter doesn't reach the 38mm:  By the way: if it's any help, the coin weights 26.50g. It's 0.23g short, which due to the amount of wear look right to me.

The bottom scale is in centimiters (the numbers indicate centimiters and each line is a milimiter)
The top scale is the one in inches.

Interesting. No, I hadn't noted your Morgan question (odd for me not to see a question about a Morgan  ). The detail images certainly appear to show a genuine coin - although likely polished as you'd mentioned. Insufficient wear exists to explain the diameter discrepancy; the US Mint was more than capable of that much accuracy. Have you measured the diameter at various points, against the possibility of a slight rim ding?

I took a couple of pictures more, and I was comparing them with my other Morgan dollars; and I have to say that if it is a fake, it's a pretty good one. Everything matches: weight, design, silver content, etc... just the diameter -well, and the colour, which is slightly darker- are wrong. I did measure the diameter all around the coin; it's the same everywhere: 0.2mm shorter than 38mm. I'm really puzzled by this coin; and I really need to find out if it's authentic, as if I'm goint to return it I need to do it now. Here are the pictures:

I just checked your mention about the insufficient wear on the rim Dave; and you are right. All my other Morgan dollars show more wear on the rim, yet they all reach the 38mm.

You're right - if this is a fake, it's a good one. It's accurate right down to the slightly-irregular date location - a little left, a little low - which isn't normal for Morgans in general but characteristic of many 1896's. So, if it's a fake, it was cast from a genuine 1896 rather than some generic Morgan die with a date punched in. Yet, the details are sharp enough to discount the idea of a cast. In your second detail image above - the one with BUS - I note some discrepancies in the rim. There's a line perpendicular to the reeding, and the area nearest the obverse seems to have a void. Furthermore, the reeding itself seems a bit shallow to me. I'm tentatively thinking that: 1) It's a real coin with a planchet irregularity - maybe the composition is a little "layered" as opposed to a nicely-mixed alloy, and the edge "collapsed" a bit under striking pressure, or.... 2) The collar itself was irregular. They were somewhat conical in design, smaller in diameter on the obverse end than the reverse end (obverse was the "hammer" die) to aid in ejection. Perhaps this one was just that slight bit out of spec, and it's a feature that hasn't been noted yet for whatever reason. They may have caught the discrepancy and removed the collar from service before a large number of coins had been struck, or.... 3) Based on the obverse detail I called out above, it could possibly be a "tilted partial collar," otherwise known as a "railroad rim." This is an interesting error in which the planchet is not fully seated in the collar when struck, allowing some or all of one side of the rim to ride over the collar. That would make it a very interesting specimen; it's not a common error with Morgans. I'd keep the coin either way - if it's fake, it has collector interest due to its' accuracy. If it's something else, it has interest due to whatever that "something else" might be.

Yes, I was about to mention that this coin couldn't be a cast. I can't take a good enough picture of it, but when looking the coin through a magnifying lense you can see some remainings of the original luster around the lengends and figures. I was inclined to believe it's authentic, but now that you have explained exactly why, I'm rather convinced. Glad to know it could be an error or a rare specimen; never had one of those.  Thanks Dave Last doubt (I promise). What do you think about this coin; doesn't it look like it had the tonning painted (look at the center of the coin). I just bought it, but I wont pay until Monday; so it would be cool to know if it's a fake beforehand... Maybe I'm a bit paranoid -since none of the coins I suspected so far were fakes-
