alexbq2 Posted May 11, 2008 Report Share Posted May 11, 2008 This is very nice! I only saw this a few times and had one chance to buy which I blew. Congratulations on a very nice and rare coin. Maybe a silly question, but is this a coin made from the dies that belonged to CPM and then were altered for CM mint, or did the P just fall off the coin? Also, Mike I saw you bought that CPM 5 kop overstrike, congrats! I had my eye on it but alas my economic stimulus is spent I did purchase this coin from the same seller though, go ahead count the wings http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...em=120255903871 Link to comment Share on other sites More sharing options...

Mike Shaver Posted May 11, 2008 Author Report Share Posted May 11, 2008 Nice 1771 overstrike .. my kind of coin. Being an Ugly Copper Person makes it even better. About the 1764 CM .. Brekke says that it is an altered die. Just find it interesting. Doubt if it is very rare or valuable .. mike Link to comment Share on other sites More sharing options...
alexbq2 Posted May 20, 2008 Report Share Posted May 20, 2008 Check out this monster! Not only is it at least a triple strike, it is also the heaviest 5 kops I've seen so far 58.75 grams! BTW, Mike did you get your overstrike yet? Link to comment Share on other sites More sharing options...
Antikvarius Posted May 20, 2008 Report Share Posted May 20, 2008 Here are some two interesting ones from this series: Link to comment Share on other sites More sharing options...
gxseries Posted May 20, 2008 Report Share Posted May 20, 2008 Alex, I'm afraid there are samples of 5 kopeks that weight easily more than 60grams, but rarely anything over 70grams, much less any closer to the sample that I own: 76.4grams... Thickness of about 5.5-6mm. Does make you think for a while what kind of edging technology that had back those days - I'm sure it must have been able to do about 1cm thick.

That must be some kind of a record!? I have one that weighs half as much, but I’m sure there are skinnier pieces around. Link to comment Share on other sites More sharing options...
Mike Shaver Posted May 21, 2008 Author Report Share Posted May 21, 2008 Alex .. the 71 is BEAUTIFUL. We UGLY copper people know true beauty when we see it. Also got my expensive overstrike. It is worth every penny. Am going to put some fakes on the other thread soon. Have Plates, Siberian etc. Thanks for show and tell .. mike Link to comment Share on other sites More sharing options...
DJB Posted May 26, 2008 Report Share Posted May 26, 2008 Here's a piece that you people might find interesting. This is a 15 kopek coin from the USSR 1925 with what appears to be a minting error. USSR 15 Kopek 1925-Obv. USSR 15 Kopek 1925-Rev. Obverse- Enlarged If you look at the enlarged image of the obverse side, you'll notice a mirrored image of the 'OPEE' of KOPEEK in Cyrillic lettering between the hammer and sickle and the sun.

alexbq2 Posted May 26, 2008 Report Share Posted May 26, 2008 A die clash!? Link to comment Share on other sites More sharing options...
DJB Posted May 26, 2008 Report Share Posted May 26, 2008 A die clash!? Thanks. I was trying to remember the type of error this was. That's what I was thinking too. Maybe a coin got stuck in the die, and embossed part of the reverse pattern into the obverse side during the striking process. Why more of the reverse pattern isn't showing, however, is not clear.

As was explained to me earlier, a die clash is when 2 dies collide without a coin planchet between them. This collision damages one or both dies living a partial coin like imprint on the damaged die(s). So when a coin is struck with such a die, it leaves an imprint amidst the expected design details. On the over hand if a coin gets stuck in the dies (brockage) one side of a coin is completely replaced with a mirror imprint of the coins over side.
