Because France produced 11 coins in 1988 that had a denomination of 10 Francs. You need to be specific if you want any kind of assessment from CT members that would be anywhere useful. Also…pics. CT cooks with pics.
@King_George_Va …from your pic you still mean 10 francs, and NGC World Coin Catalog revealed the following: KM #964.1, bi-metallic, 6.5 grams. Not proof. Not silver. Not gold. Not platinum. It has segmented reeding. If it graded MS60 it lists a value of $4.50 USD. OR KM #E140, bi-metallic. Not proof. Not silver. Not gold. Not platinum. There is no other information about this KM#. There are no listed values, no identifying data nor any thing else to distinguish this one from the KM #964.1 or why it is labelled with a different #. Further research ( by you ) would be needed to compare the 2 for a definitive determination…imo…Spark
This is what I found but now I do not know which one I have. KM #E140 (Essai/Pattern Coin) Type: Essai (Pattern/Trial Coin) These are prototypes or experimental coins not intended for general circulation. Metal Composition: Typically made of base metals such as aluminum, copper-nickel, or other alloys (not silver). Design Features: The design may closely resemble KM #964.1 but can include differences like the word "ESSAI" engraved on the coin. Mint marks and inscriptions may vary slightly. Rarity and Purpose: Essai coins are rarer and were struck in limited numbers for testing or presentation purposes. Highly collectible among numismatists. KM #964.1 (Circulating Coin) Type: Circulating Coin Issued as regular legal tender for everyday transactions. Metal Composition: Silver: 90% silver (.900 fine) with a weight of 25 grams. The actual silver content is approximately 22.5 grams. Design Features: The coin features official, finalized designs approved for circulation. Common design elements include Marianne (a symbol of liberty) or other traditional French motifs. Purpose and Availability: Struck in larger quantities for circulation. Less rare than Essai coins but valuable due to the silver content. Would like opinions Thanks
Well, the info I posted earlier for the KM #964.1 makes no mention of silver content but the weight listed was 6.5 grams in total, meaning it is impossible for it to have 22.5 grams of silver. Your info does not jive with that of the NGC World Coin Catalog. What is the source of your info? It seems we have a conundrum that will force us back to the drawing board…Spark
I'll weigh mine next time I'm in town. I received the information from ChatGPT. I do not put faith in its answers but it always stimulates more research.
