Got a bunch of coins for about $20 recently. Here's half of the junk bin picks to start. My ID attempts: Ireland 1/2 Penny 1942 Denmark 1 Krone 1962 Kenya 1 Shilling 1969 Tanzania 1 Shillingi 1966 Fiji 1 Shilling 1957 Japan 100 Yen Showa 50 (1975) $0.75 face value for 10 cents... Japan 10 Yen, reeded edge, Showa 27, 29 (1952, 1954) Japan 1 Sen Showa 18 (1943) Norway 5 Øre 1953 Germany 5 Pfennig 1913 Germany 2 Pfennig 1908 Germany 1 Pfennig 1900 Switzerland 5 Rappen 1953 Hungary 10 Fillér 1894 Canada 1 Cent 1929, 1934, 1936 Canada 5 Cents 1927, 1936
Second half of the junk bin picks: Costa Rica 100 Colones 1997 Colombia 10 Centavos 1966 Mexico 5 Centavos 1928 (not in bad shape. Not sure which of the 2 date varieties) Mexico 5 Centavos 1946 Mexico 10 Pesos 1998 (this also has 2 date varieties, not sure which) Luxembourg 10 Centimes 1930 Sweden 1937 1 Öre Netherlands 1925 1 Cent Netherlands 1897 1 Cent (Lowest mintage date of series) Netherland East Indies 1938 1 Duit UK 2 Shillings 1956 Yugoslavia 50 Para 1973 Czechoslovakia 3 Haléře 1953 Russia 2 Kopecks 1905 (Unfortunately in poor condition) US Token "EP" (Easy Picker) golf ball vending machine denomination 2 Brasil 5 Cruzados 1987 Brasil 100 Réis 1938 Panama 5 Centésimos 1966 Venezuela 25 Centimos 1965 (Single-year type, but they minted 240 million!) Chile 20 Centavos 1921 Nothing spectacular, but a few fun finds at 10 cents each. The most valuable might well be the golf ball token which can go for a few bucks...
Now for the 15 older mystery coins. #1 I feel like this one has enough to be IDed, but I'm stuck. Copper, 28 mm, 11.35 g Ob: Portrait? Rev: "PVBLIC COMMO DITAS" in a wreath? Italian? Ancient? Suggestions welcomed!
Haven't found an exact match, but I think it's from the Kingdom of Naples. It's very similar to this 1622-3 Felipe IV 3 Tornesi (33 mm) but mine is 28 mm. It's about the size of 1 grano, but I can't find the exact inscription in Krause. Photos not mine.
One could accuse me of having an overactive imagination, but for this one I think I have a positive ID. 7.7 g, 26 mm, copper. From the coat of arms on the reverse I know it's Kingdom of Naples, and the script letter right of the hair matches Filippo IV. I can just make out a bit of an 8 for the date, which I think is part of 1648. It's a pretty close match to the one pictured on Numista, though a bit worn down. Naples, 1 Grano, 1648, Filippo IV
Another Puzzler. It's hard to find an exact match, but I think it may be: Papal States (Gubbio?), 1 Quattrino, Benedict XIII, 1724-1730. 2.44 g, 20 mm Crossed keys on the top of the obverse pointed me to the Papal States. The arms definitely look like Benedict XIII, and I can make out "BE" at 7:00 on the obverse. Reverse looks like a standing figure, probably St. Ubaldus. Here are a couple (different) coins with similar attribution. I wish Krause had pictures of these old Italian States minors, but they don't.
You might find “Corpus Nummorum Italicorum xx” a useful resource . 731 pages text is in Italian lots of plates. Your coin from Naples looks like it’s listed on page 277 No159.There is no photo but the structure of the reverse legend in 3 lines matches up.You can find a link to the work at Forvm Ancient Coins.It might help with the other coins you have.The number I gave you was for the first coin you pictured.
I wasn't sure I could ID this one, but I think I have the type and year: Sicily, 2 Grana, 1795, Ferdinando III. 6.4 g, 26 mm, Copper Obverse: Eagle, "FERD D.G. SIC. REX." Reverse: "UT COMMO DIUS 1795"
Another tough one. Crossed keys make me think Papal States. I think the text reads (approximately): ob: "P M A VI" ... "INN XII" (Pontifex Maximus year 12) rev: "[SANC]TVS" Saint (Peter? Paul? Usbaldus?) So it's probably a quattrino of Pope Innocent XII, such as this one. If it is year VI, I think that would be 1696 The saint text looks like "PAV" for "Paulus" to me, but I can't find a St. Paul type on Numista that's a close match for the date/pope/metal of the coin. Mysterious.
A crudely-made irregular copper coin. 2.7 g, 16 to 19 mm Obverse is a left-facing eagle, but it's too old to be from unified Germany. I'm thinking perhaps the Duchy of Modena and Reggio. Compare to this 1 Bolognino (1737-1780) for my closest guess at a match.
Your musings are about as good as anything as I'd come up with. I agree that the coin in Post #11 is likely Papal States.
