That specific coin can be worth anywhere from 10 dollars to 500 dollars. It depends on the condition and who your buyer is.
The value of a 1911R c20 Italia coin can vary depending on its condition, rarity, and current demand among collectors. It is recommended to have the coin appraised by a professional coin dealer or numismatist to determine its precise value.
Such a coin is fairly common and is not made out of any precious material and since it is in a necklace, there is no coin collector value. Any value would come from the necklace itself, most likely scrap silver/gold if the chain or bezel was made out of that. In short, the coin is worthless and the only value comes from the necklace part itself.
The coin you are describing appears to be a 1941 Italian coin, possibly a 20 centesimi piece, which features the depiction of a historical figure or symbol. The inscription "RXIX C20" might refer to a specific mint mark or cataloging designation. To determine its exact value, you would need to consult a coin catalog or a numismatic expert, as values can vary based on condition, rarity, and demand. Generally, such coins can range from a few dollars to more, depending on these factors.
