These are nice silver coins from Albania. The pattern is the same on both 1 and 2 denomination coins, but the 2 franga ari is larger than the 1 frang ar, and, of course, the denomination is spelled out specifically on each.
1 FRANG AR: 0.134 troy ounces silver
2 FRANGA ARI: 0.268 troy ounces silver
These coins are quite rare. Only a few were minted and not many survive. The 1937 date is worth a tad more than the 1935 date. The listing below shows approximate catalog values for the 1935 dated coins.
Chile used the obelisk and volcano pattern on both peso and reales silver coins between 1817 and 1834. The denomination is inside the wreath over the volcano. Our main picture (upper left) show a real, and the secondary picture (lower right) shows a peso. All these coins are quite valuable. The catalog values below are very approximate, and desirable coins can easily exceed these values.
worn: $80 US dollars approximate catalog value
average circulated: $450
This beautiful coin was minted only in 1886AD, 1293AH by the Islamic calendar, Murad V, and regnal year 12. The coin contains 0.2391 troy ounces of gold, so it can never be worth less than its gold value.
worn: gold value
average circulated: $400
well preserved: $500
fully uncirculated: $600
The coin in our picture is a very nice example. It was sold by Baldwin's in London for 340 British pounds (about $530 US dollars) during a 2014 auction.
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.
