The process of separating and purifying metals is called refining. A quick Google search didn't find a simple explanation, but this one isn't too...
[IMG] I never knew there were gold $1 coins.[IMG] I won't make that mistake again.[IMG]
Probability that it's a fake - 99.97% :(
You don't mention the date on the coin, and although I don't collect U.S. coins, I have checked the Red Book and found no dollar coins with indian...
Maybe they never did get Abe off the cent, and a time traveler lost this one. :D
Except for the half dimes (1.24-1.35g), and possibly the WW II silver "nickles", U.S. 5-cent pieces have always weighed 5g. Interestingly, both...
Sorry[IMG], I missed the caption which identified the country and year. The 1950 Canadian cent is KM#41, mintage 60,444,992. The current Krause...
I'm assuming from your question that it's a penny, not a farthing or half-penny which share the same design in bronze. If it's a 1937 Canadian...

Actually they sell many more than 4 books and catalogs, but the Standard Catalog of World Coins is presently sold in four big city telephone...
In the case of Japanese mint sets, generally the set in its original holder is valued quite a bit more than the individual coins, although the...
Sorry, since my mind reading license was revoked I can't identify coins without a picture[IMG], or at the very least a good description[IMG].
Based on the shape of the characters, I think you have it approximately upside down. That character at dead center may be a figure 1, but I still...
What I don't know about Lincoln cents already fills several books. Here are the Red Book's 2,000 words on the subject: [IMG]
No way, no how! It appears to be dated 2036 at the bottom, in Indian Sanskrit script. That would be approximately equivalent to 1980 in the...
Another sad example of form follows function - stackability of coins has gained such tremendous importance as the use of money has become more...
Get its two-tailed mate here, for $4.95 + S/H :D .
Verrrrrrrry interesting! Your coin does not appear to be a genuine Platinum American Eagle, although the obverse is identical to the U.S....
