  1. I haven't seen these coins in person, as I understand they are all genuine common coins with altered dates. I'm not sure why Mr. Markov did not detect the tempering while examining the coins, I have read some complaints about his character from some people on that forum, stating that he would not accept returns after the auction item was determined to be less than genuine, and that he was rather rude over the phone.

     

    I do not know him personally and cannot comment on his character or behavior.

  2. Brekke had bought this very coin from WWCC around 1990 outbidding me. It appeared again in 1993 at the Brekke collection sale (#1233), where I was outbidden again. Now I tried the 3rd time - again in vain.

    Maybe we'll meet again :crazy: ?

    Hope you get it next time!

     

    I have a feeling that the pictures in the catalog do not do it justice. Is it as nice as that Markov coin that sold a few years back?

  3. I do not think that it was a real sale on Sincona. The coin is just too ugly.

    I am still looking for a decent 1843 and 1845CM… The only ones I am missing from the set. 1/4 and 1/2 CM sets were completed with this lot. I liked the lot a lot (pun intended :bgreen: )

     

    BKB do you want this one? Cleaned but not too ugly:

  4. Congrats to BKB on winning a great lot! I'm surprised that the auction catalog ranked 3 kop 1839 CM as scarce, I would have thought it would be listed as rare. The Sincona coin was all messed up and fetched something like 7000 CHF!

     

    And no pictures listed in the catalog?! And still no website?!

  5. I think there were several theories. Basically to get this 'Positive' and Mirrored artifact of the reverse side of the coin, the die has to have a negative impression on it. So there has to be contact and some form of interaction between the 2 dies. The 2 theories that I liked and thus remembered are as follows:

     

    1) There is a dies clash, and one of the dies is heavily damaged, there is an are with 'Positive' impression of the opposite die on the damaged die. The damaged die is filed down to remove this damage. The metal in the filed down are is softened, and over time indentations develop from heavy use, that end up producing 'Positive' impressions on coins. I'm not a metallurgist so can't tell if this is likely.

     

    2) The other theory had to do with rust. Let's say that dies are in place, but the press is not used. So the two dies are just sitting there in contact with each other. Over time rust sets in, rust in the contact areas is more aggressive (not sure why). After some time, the press is prepared to be in use, the workers scrub the rust off, but now there are indentations in the places of die contact that cause Positive impressions on coins.
