These are from Prague, I received these a few years ago, and I'm wondering if they are gold and silver or just plated and what value they are. Thanks!
Have to get an X-ray to be sure its not plated (non-destructive). Or simply sacrifice one by punching the coin with a steel punch & hammer (destructive). Just a guess I would say platted. Traci
A silver or gold medal will usually (but not necessarily) have some info about the precious metal content, e.g. "825" or "900". Cannot see that here, so I also think they are plated. Nice view of the castle/cathedral and Charles Bridge on the upper (golden) one though! Christian
i believe gold can be ascertained by "specific gravity" not sure of the way but i think it (the coin) is weighed in water, your friendly gold merchant could tell you. mike.
I think I'll grab my metal detector and try it that way, I'm pretty sure they aren't worth much though :/
I think I'll grab my metal detector and try it that way, I'm pretty sure they aren't worth much though :/ ...................................................................................................... if you work at it hard enough at detecting there is money to be found, last night i decided to go through all the gold rings i've found in 29 years of detecting. first i separated the rings into their "carat value" ie. 9ct, 14ct, and 18 ct.i then weighed them and worked out the amount of "pure" 24ct gold in them, it came to 363.46 grams of pure gold, i had to make a "guesstimate" at how much the stones in them weighed but i feel i am fairly close on the quantity, i did not differenciate on whether it was yellow gold or white gold, so there is gold to be found on the beaches. mike.:thumb:
yeah I need to bring mine down to the beach sometime, I live a bit inland so I'm going to start detecting around old barns and around stone walls. I live in an old farming community but now it's turning into a city. So I need to hit these places up before they're torn down and a walmart/gas station/dunkin donuts is put in
Probably a bronze or bronze-plated coin at top and a silver commem. below. There are other gold and silver Charles Bridge (or Karlus Most) coins out there commemorating this historic site. See the Gild? site: http://www.zlate-mince.cz/UK_Start.htm http://www.zlate-mince.cz/CRM_Karluv_Most.htm Look around on the Czech Mint Co. page to get an idea of metals they use: http://www.mint.cz/ And the Czech National Bank has a Numismatic page, maybe there's an archive of your coins there: http://www.cnb.cz/en/banknotes_coins/numismatics/ Incidentally, the region around Prague was historically rich in silver and the groschen was a coin widely used in medieval Europe. There's info online about the medieval coins such as the groschen: http://en.wikipedia.org/wiki/Prague_groschen
Wow thanks for the info! I have to say it must be plated, so I'll hold onto them in hope of a good resale. Thanks!
Mike is absolutely right. A specific gravity test will tell you what you have. Doing a SG test takes a bit of skill but it is really quite easy. Below is a link that explains the process: Specific Gravity by J. T. Stanton
