IMHO! So you are trying to say that numerals "17" on 1757 coin are shaped like this because there is underlying "26" from previous (1726) coin in that same place? If so, this does not look to be the case to me. "1" of the date looks like this on many coins, and sometimes "7" have that "tail" on some coins of this period. Besides "6" is bigger in size, wider and closer to the center than "7" on the other coin. IMHO. WCO

IMHO! Overstrike have nothing to do with overdate. Overdate is made on the same die when new date punched over the old one. Here we have two different dies from two different coins, just one coin is struck over another. Best regards, WCO

I did not comment the way you collect your coins, anyone can collect whatever he wants. I just said that finding those 3 coins in choice condition is difficult. Some people with enough money would want to buy those 3 coins in choice grade but unable to locate them. With couple more exceptions (like 1926 5 Kopecks in Proof and 1927 5 Kopecks) the rest of 5 Kopecks is quite easy, just possible to buy for whatever money. WCO

In some Russian catalogs there are listed coins (1 to 5 Kopecks) of 1929 in Proof. I also heard rumors about existence of 1931 silver 10, 15 and 20 Kopecks in Proof (not known Novodels or originals). I am wondering if anyone can provide pictures or credible references that can prove existence of such coins. Thank you in advance.

The challenge is not to obtain 1933-1935(old) 5 Kopecks but to find them in collectible condition. Preferably Unc. IMHO.

Thank you for your opinion, ccg. Is so huge difference in weight (almost 0.8 gram more than nominal) is known for this kind? May be someone else may provide their opinion on authenticity. Thank you.

That someone is me. I purchased the coin and received it today. Now I have doubts, I weighted it and it is 26.38 gram (normal weight in Krause shown as 25.60 gram). But may be that is allowed weight for this kind of coins since their silver content is anywhere between 500 and 880 silver. So I am wondering may be someone knows for sure is this a real (authentic) coin or fake. Any opinion is greatly appretiated.

Anyone knows if this is authentic or not? http://www.ebay.com/itm/140893991451 Thank you in advance.

Comparing 1970 and 1976 5 Kopeck pieces is pointless. Most of 1976 5 Kopeck pieces have the same obverse (of 1958) as 1970 coins and the same reverse. Differences if any are very minor and related to individual die imperfections. There is a good chance your coin is a fake made out of 1976. Use 40-x magnification to find out. WCO

Looks as Pyrrhic victory to me. Coins are good though. WCO
