Triple-9 fine coins are bullion pieces not intended for circulation and they should be marked .999. Hallmark / stamping : Ag 999 And I strongly suggest to buy from the reliable supplier because we even got the sample from USA which with hallmark Ag 999,but it is just with 80% silver after test.
One way to know a coin is not silver is to check it with a magnet. If the magnet sticks to the coin, it is not silver. If the magnet does not stick, it still might not be silver. You can test it, but to do that you need a test kit.
Coin silver Selmer's are stamped on the main body "Coin Silver" Matching serial numbers on all pieces prove they are all solid silver.
The best thing to do is take it to a coin dealer.
in order to tell for sure, you would need to take it to a coin specialist. most coins now are a mix of zinc and copper. if your coin truly is silver, it is probably very very old and worth a good amount of money.
I think you would have to be a physicist to do that. It would be easier to identify the coin by nation of origin, date and denomination, and a coin guide book will help do this, and the book will tell you what metal the coin is made from.
No general circulation British coin contains any silver. If you have any modern British coin with a silver content, it will say so on the packaging it was sold in. This will include the percentage of silver and very possibly, a "certificate of authenticity".
The color is different. The silver is more reflective. If you cover the coin with a Kleenex you can barely see the CN coin but the silver one shows through.
If it is a "Silver" coin, it will say so on the case it came in.
Yes, it can also contain silver. Experts can tell by holding the coin & observing its edge & by its weight. Clad coins are usually lighter
A genuine silver coin produced by the Royal Mint will be in protective packaging indicating what the coin is made from. It should also include a certificate of authenticity.
You can't unless you pay the $20+ to send your coin to NGC/PCGs even under magnification the ordinary person cannot tell the difference between a pf69 and pf70 coin. Of course, it is easy to tell if your coin is uncirculated or proof, a proof silver eagle will have very shiny, mirror like fields that are easy to see yourself in. An uncirculated silver eagle will be shiny, but won't be mirror like. Also, the raised part of the coin will look frosted on a proof coin but not on an uncirculated coin.
The U.S. has made many silver coins. Please be more specific and post new question.
