I like French coins. The designs are always interesting, artistic, and well done. This design is no exception.
This is a complicated series of coins. It runs from 1933 to 1952 with the same patterns on front and back, but several variations apply. Some coins are made out of nickel, others aluminum, and still others aluminum-bronze. Also, some coins have mint marks and others do not.
In general, for most coins except those noted below, here are approximate catalog values:
What a fantastic piece! First I thought this was an AE drachm from Alexandria, but the weight of almost 50 grams is far too high for that. After further research I can conclude that this is a rare medallion strike from Pergamon (Pergamum) in Mysia struck during the reign of the ever-'photogenic' Roman emperor Severus Alexander.
The reverse shows the deity Asklepios, an ancient Greek god and personification of medicine, standing with his well-known serpent-entwined staff that even today is used as a symbol of health-care and medicine. He is standing in front of an enthroned Zeus; a deity who should require no introduction.
I like toned coins. If I were looking for a South Africa 3 pence for my collection, I would pay more for the specimen in the picture because is has spiffy rainbow toning. Over the years this silver coin has picked up impurities from the atmosphere and those impurities have reacted with the surface to create coloring effects. However, I am in the minority. Most collectors like their silver coins blast white, or completely untoned. Dem guys don't know what dey's missin'.
Costa Rica changed its money system in 1920. The preponderance of coins minted since then all have the same pattern of an ornate crest with mountains and sailing ships. The individual denominations, 5, 10, 25, and 50 centimos and 1 and 2 colones (there are 100 centimos in a colon) appear on the reverse side of the coin.
Just about all these coins carry very low collector value. They are minted in various metals, including brass, bronze, aluminum, copper-nickel, and stainless steel.
This play money token is part of a series made in aluminum by Tracies, Inc. of Massachusetts. This particular series dates to the mid-20th century and contained a 'half buck' and 'henny penny,' among others. Tracies also made play money out of other metals (even wood) and there are collectors who seek out these items.
This does not mean they are valuable, however, because they are still just mass-produced novelty items -- an eager collector might pay one U.S. dollar or two to acquire a play coin they are missing from their collection.
I think I understand your request correctly, Mark, but maybe not. It sounds like you have a bracelet with 6 Maria Theresa thalers. You further emphasize that no solder has touched the coins in the jewelry making process.
Assuming I am correct, we can use the coin in the picture to give you an idea of the value of your coin. CoinQuest thanks SESAM Basel for use of their coin photo. SESAM has this coin on sale for about $200 US dollars. The coin is in wonderful numismatic condition and is easily worth that amount.
