         | and therefore worth a certain amount of currency.
         | 
         | I think a much more common thing was to shave off part of the
         | precious metal and keep it (since the metal is worth money).

         | 
         | If it's still gold/silver, but different design, it's just a
         | foreign coin. They weigh it to figure out the worth.
         | 
         | The tricky part is if the coin is clipped. Take a look at dime
         | or quarter: notice the fancy edge? That was so if the edge got
         | clipped, it's no longer fancy, and you can tell it was clipped
         | and weighs less. This is actually an important property of
         | silver and formerly silver coins: the different value coins
         | change weight in direct proportion to value. So a quarter
         | weighs 2.5x as much as a dime.

         | (edit: got grams and ounces mixed up)
         | 
         | Monetary denominations are a units of weight. So you weigh
         | them. Mass and volume. It is hard to replicate silver and gold
         | with cheaper metals.
         | 
         | Back when the USA was on a bimetal standard you didn't
         | technically have to have the money minted to have a "dollar of
         | gold" or a "dollar of silver". It was same during the Roman
         | era, although obviously they didn't use monetary units based on
         | the Spanish Doubloon (ie: pieces of eight, or eight reals)
         | 
         | So if you have 26.73 grams of silver you can say "I have a
         | dollar in silver". It doesn't matter if it was stamped or not.
         | 
         | Of course, that is worth about $21 nowadays since we no longer
         | use money in the absolute technical sense, but currency based
         | on the credit of the Federal government and inflation is a
         | bitch.
         | 
         | To this day if you weigh "silver coinage" in the USA it more or
         | less weighs the same as it did before. Although obviously it is
         | not exact anymore since our money is no longer silver based.
         | That is if you take 10 dimes, 4 quarters, or two 50 cent pieces
         | they all weigh about the same. Of course Nickels and Pennies
         | don't work since they are not silver-based.
         | 
         | This is why you see in old cartoons miserly people biting
         | coins. They are theoretically checking to make sure it wasn't
         | plated lead.
         | 
         | People would shave coins to get little bits and pieces off the
         | edges so it wouldn't affect the appearance. Which is why more
         | modern coins are stamped with ridges and decorations near the
         | edges.
         | 
         | And, of course, as the Roman Empire fell they would debase
         | their own currency in order to cover debts. So they would
         | reduce the size of the coins or try to mix different metals in
         | with it. Effectively the government was counterfeiting their
         | own coins.

               | Union Latine coins from the 19th century (mostly Swiss,
               | Belgian, and French francs) and some British sovereigns
               | are quite easy to get at metal value (edit: I mention
               | these because they are somewhat old; there are plenty of
               | 20th-century coins in the same situation). They are
               | convenient because everyone (interested) knows how much
               | they weight and therefore how much they are worth, give
               | or take some Greek shenanigans.

               | Yes, the coins were heavily debased during this period,

       | * "When a Roman emperor or European king would mint new coins
       | with his portrait (or whatever) on them, did they take the old
       | ones of previous rulers out of circulation? Or would citizens be
       | faced with a myriad of coins with different faces of different
