What does high quality replica means?
It means a copy of a high standard, but not the original.
Whats the value of a 1958 ghana ten shilling coin with serrated edge. andis it a proof coin or not.?
All 1958 ten shillings are proofs. There were no circulation coins struck in silver, they were either bronze or copper-nickel. If you have a coin that is dated 1958 at that weight, it's counterfeit.
I have one England ancient coin made 1086, how can to know the correct value of this coin ?
You probably have an English 1 silver penny, Paxs type(or called the Paxs Penny) from 1083-86, under the Norman King William 1. There are many varieties and many mints producing this coin, so unless I(or another numismatist) closely examine your coin I wouldn't be able to tell you the correct value of it. Price for Very Fine grade with all the edge letters and cross visible starts from £400. UPDATE: It's a St Helena & Ascension 50 pence dated 1986(not 1086), issued to commemorate the Royal Wedding of Prince Andrew and Sarah Ferguson on July 23rd that year. This coin type has 3 versions. The most common version is made of copper-nickel alloy(has dull gray color), with a mintage of 13,000 and valued at US$4 in uncirculated condition. The other 2 versions are in precious metals and not commonly found. One of them is the sterling silver version, with a low mintage of 2,500 and has market value about $30 to $32. Another precious metal version is made of 0.917 fine gold, with a mintage of only 50 coins and valued at about $1,300 to $1,500. If your coin is the copper-nickel version, then I'd suggest that you keep it rather than sell, coz the most a coin dealer can pay you is about $2, and in my opinion it's not worth the effort and time. Furthermore, coins from St Helena & Asc are not easy to find, despite the low value. Else if your coin is the gold or silver version, then you can try to sell it to a coin dealer or collector. You might not be paid the price I quoted here, but at least you know what to expect.
Is this coin fake?
I have 2 of what seems to be seated liberty silver dollar coins. One is dated 1844, the other is 1845. They are marked CC, which according to a site means they were made in Carson City. Thing is, and I can't find that site anymore, I remember reading that Carson City silver dollars weren't made during the years of 1844 and 1845. So does that mean that this is a fake?
Is this coin real or fake & how much value?
I recently found this coin in a bag i havent used in years, forgetting where i got it from. But when i looked on the internet it appears to be a new england shilling. With the words NE on one side & the roman numerals XII on the other however there are also the letters OPY on it. Idk if OPY stands for something or if it was supposed to say COPY & the C for some reason didnt get hit on the coin
