Well, if I "unlearned what I learned", I would say,
No
No
Yes
Yes
But I know that's wrong for some of them.
Your test isn't really "fair", because we don't have the coins in hand. For one of them you could know by feel (weight) that it sure wasn't silver. And the American one, you could always check the rim.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

The experiment was visual ,, and true the US coin could be looked at from the edge but even some of the 40% silver Kennedies and Ike's show a sandwich layer .
any way here are the answers
coin number 1
1905 Mexico 5 Centavos
Nickle
coin number 2
1957 Mexico Hildago 5 peso
720 Silver
coin number 3
austria 1 shilling
Aluminum
coin number 4
US 1964 Kennedy
90% Silver

Thanks for the answer Metalman. That was a tough one doing visually. It's still a tough one even when you have them in person (at least for me). I can figure out most of the US coins but am still having a problem with others. |

It can be really tough by looks alone to determine the composition of most coins ,, There is no real substitute for knowledge.
Neither sight nor hearing are fool proof ,, there will always be exceptions to both .
This was just something fun for a sunday afternoon ,, hopefully the result will be time in the books and coins .
Sap I know that you knew some of these coins perhaps all of them and would more than likely know their metallic composition ,, Knowledge is indeed King !!

Do you have any favorite books for the Non-US coins? I have several coins from outside the US but not sure what the best resource is out there. I use the Red Book for US coins. |

I use Krause standard catalog of world coins alot , I also use several different web pages for particular type or country coins .
This one is pretty good for general knowledge .

Thanks. I will check out the Krause standard catalog of world coins along with the link you have provided. I need to figure out how to take a good picture of the coins I have. I need to start reading the other forums on this site.

This looks like it could be a good topic for the quiz/coontest section. Kind of like Saps contest on world coins, and this one could include composition. I will have to look into this when I get back from my trip on the 22nd and run something. Now I just need to think of a prize!!!

Until she passed, I had the most fool proof method going for IDing silver. I would just hand it to my grandmother. If she immediately scrubbed the crude out if it with silver polish I knew. She could spot silver at a yard sale from 100 feet. Jim   |
