Napoleon's 1, 2, and 5 franc silver coins all have the same pattern shown here, but the size, of course, is different from denomination to denomination. In general these are valuable coins, with catalog values as follows:
1 FRANC, 22 mm diameter, 0.134 troy ounces silver
worn (like our picture): $10 US dollars catalog value
average circulated: $20
well preserved: $45
fully uncirculated: $150
2 FRANCS, 26 mm diameter, 0.268 troy ounces silver
The coin in our primary picture, at left, is a genuine Chinese Republic dollar from 1916. It sold in a 2013 Stacks Bowers Ponterio Auction for an amazing $15000 US dollars. The strike, luster, and eye appeal of this coin sent the price through the roof. 'Normal' coins would be worth much less.
The two coins in our secondary picture, at right with blue background, are cheap replicas and reproductions. One is made of tin (or other base metal) and one is made of gold-plated silver. These are worth a few dollars each. As always with valuable coins, you must be aware of counterfeits, and this goes especially for Chinese coins.
It is not difficult to discern why they call this a 'fatman' dollar. President Yuan Shikai of China was not all that fat, but it sure looks like he was in his profile on this coin. There are two denominations, 50 cents and 1 dollar. Both coins look very similar, but their size is different.
Evaluating these coins is not easy. First we list some very approximate catalog values:
50 CENTS (1/2 YUAN) 30 mm diameter, 0.306 troy ounces silver
worn: $10 US dollars approximate catalog value
Denmark issued a bunch of 2 kroner coins during the early 1900s, and they all have neat patterns. It would be a worthwhile collecting endeavor to assemble a set of nice-looking examples, one from each of the 12 different patterns. It would not be overly expensive, but it would not be cheap, either.
While early 2 kroners were minted in silver, by the time 1924 came around Denmark moved to aluminum-bronze. Mario's example is in such good condition, it looks like gold. But, alas, it is not.
This is an old jeton (counting or gaming token) from the Spanish Netherlands under Charles II dated 1681. The inscription IPSIS AUGETUR AB UNDIS means THE INCREASE FROM THE WAVES. The woman on the front seems to be harvesting that increase and storing it in a treasure chest.
Jetons like this are collected by a small slice of the numismatic (coin collecting) community and, even though they are old, values do not reach very high. This pattern is somewhat rare, so values are somewhat higher than common jetons.
Trudy -- You have a special coin. These old coins from Great Britain are highly sought by a group of specialized collectors who want to hold history in their hands.
The coin in our picture comes from Timeline Originals, Upminster, London. It is a beautiful example of a hammered Elizabeth sixpence dated 1561. The inscription on the reverse, POSUI DEUM ADJUTOREM MEUM, means I have made God my helper.
Don't we wish, Dayan, that these coins were made of silver. Instead, they are made of nickel, a non-precious metal.
Modern coins made of non-precious metal are worth face value, nothing more. The one in our picture is almost uncirculated, so a collector might pay a few US dollars to add it to his or her collection.

These large coins are made of aluminum-bronze, not gold. They are worth a few US cents. A collector will pay a few US dollars to add an uncirculated specimen to his or her collection.
