Hello!
How many different kinds of metals/alloys do you know are being made for coins?
I only know a few:
Silver
Gold
Bronze
Copper
Nickel
Cupronickel
Copper-nickel-zinc
Zinc
Aluminium
Platinum
Stainless Steel
Nordic Gold
Mostly one element:
Gold (most often as alloy with copper)
Silver (most often as alloy with copper)
Copper
Nickel (most often as alloy)
Iron (most often as alloy with carbon)
Aluminium (most often as alloy with copper and magnesium)
Zinc (most often as alloy)
Tin
Lead
Platinum
Palladium
Titanium
Niobium
Iridium
Alloys:
Copper-silver alloys (Billon)
Bronze (different additive elements like aluminium etc.)
Potin (antique bronze with much tin and lead)
Brass (many kinds with additive elements like zinc, nickel, aluminium, manganese)
Aurichalkum (antique brass with much zinc)
Copper-nickel
Electrum (gold-silver, silver-gold)
Steel (with many different additive elements like chrome)
many different plating, coating and sandwich combination of listed metals
Mettallic:
Alpacca (aka nickel silver, maillechiort or german silver) is an alloy of copper, nickel and zinc.
And (here comes the arguing) electricity (bitcoins and other electronic money).

A thing, issued by a legal goverment or organisation, ment to pay for a product or service. And not some fantasyobject what is made, in the first place, to suck money out of the pockets from innocent collectors...but that is my personal point of view.
I say, a coin is:
1. For a person who does not know what they are, a pretty small (or big) metal disc that usually has writing on it.
2. For a person who knows about coins, the metal disc (or for example acrylic disc) but the disc has been approved by the leaders as legal to use in public stores, shopping places and ikeas. According to true measures the word coin means any object with legal tender in public use. It can be: only 1 coin minted. It can also be a non-circulating coin, commemorative coin. But certainly not a token. A 25 euro coin IS a coin. A columbian exposition half dollar IS a coin.
You don't have to like them. But they are coins. They are lawful. They are denominated. They are in coin catalogs. They have KM numbers. It is cute how you and so many others get enraged over these matters. Don't collect it if you don't like it. Many folks here do not collect NCLT.

Hello,
I am neither a chemist nor a scrap dealer, I would like to know how you do to determine the material of a coin or token without its documentation.
Thanks

Gary Dykes posted a series of Specific Gravity tests on the website "Coin Talk", search for "GSDykes", and the words "Specific Gravity", a PDF file should then be presented. He tests many metal combinations. It is a challenge, but specific gravity tests can help!!
