I have had some success typing partial legends into the search function at MA-Shops. There are lots of older European minors listed. It also works well to confirm an attribution since the dealers usually have a picture of a coin that is in decent shape.
r6c8 could be any of the Savoy 2 denari from the early 1700s. This one (1717-8) is the closest in weight (1.65g matches mine exactly), but I'm not sure how seriously to take weight measurements on these early, irregular coins. This Sardinian one is very similar, but the ring of the crown touches the knot, and the crossovers of the knot are in the reversed direction. Date is unfortunately unreadable below the knot, and I can't make out anything on the obverse.
Here are some new photos of individual coins. I realize that many of these will never be identifiable, but we've had pretty good luck so far. Thanks for all the help. r1c10 22 mm 4.49 g r3c9 19 mm 1.48 g r2c10 23 mm 5.08 g r5c9 17 mm 0.74 g r5c10 14 to 16 mm (squarish), 1.03 g
A couple more photos. These 2 have a similar monogram. An L? On the left one I think I see "C VEL E" from 2:00 to 6:00 Right one might have "TT" at 1:00 Any wild guesses would be greatly welcomed!
Have you considered trying a distilled water soak for R2C10? This could be a possible match for that particular coin, but this possible identification is really stretching it. https://en.numista.com/catalogue/pieces3612.html
I think you may be right about r2c10. For a moment I was pretty sure I could see the loops of the ribbon and the wreath, but now I'm not sure. I'm soaking it now and will check on it in a few days. If it's any clearer afterward I'll try to post a picture. Thanks for your help on these. I'm not expecting to get rich off of any of them in this condition, but it's been fun trying to ID them.
Here's another one that's been bothering me: r4c9, 1.69 g, 20 mm I feel like there's enough detail to ID it, but I'm having difficulty reading some of the perimeter lettering. One side has a haloed figure with right hand raised inside a ring of dots, I think. I think I can make out "D" ..."EN" and "OST" around the halo. But searching for those strings doesn't come up with anything close yet. edit: Some of the Swiss Cantons have similar layouts, like this billon schilling. But the lettering is not close, and mine is heavier.
If the contents of this lot are any indication, R4C9 is probably from the Italian States. Based on the remaining lettering and design, I believe it is a Venetian 1 Soldo from 1623 - 1778, like the one in the link below. https://en.numista.com/catalogue/pieces54260.html
I think you've got the right category, thanks! I believe it might specifically be this one, from 1684-88 under Marcantonio Giustinian. When I looked the beaded ring on the reverse, one thing that bugged me is that is irregular. It starts around chin height on the left and ends at the top of the head on the right side. Of all the series of Ventetian copper 1 soldo coins, that was the only one I saw where the Numista image had the same irregularity. I don't know how consistent the manufacture was for coins this old. Mine has the text around 1:00 half off the flan, but the full text is visible on the left. The "S" of "DEFENS" seems to be missing entirely though, with no room between the N and the head of Jesus. I imagine many of these old coins from the 1600s have lots of different minor variations of the coin text, some of them not differentiated in catalogs. comparison: mine is on the left edit: Never mind--I see that the Doge's name is on the obverse ending at around the 4:00 position. Mine has "ERI" at that point (maybe "ENI") which would only be Francesco Erizzo (ERI) or Alvise Mocenigo II (ENI). I think it looks more like "ERI" so in spite of some minor differences from the variant pictured, I'm going to guess it is Francesco Erizzo, 1641-46, 2.04 g billon, 21 mm. Mine is about 0.3 g light, and the diameter is low by 1-2 mm, which could be from wear or clipping.
To follow up, here is r2c10 before and after a DI soak for a week or two: before: After: The obverse is slightly off-angled between the two photos, sorry. Either way, it looks more like the surface of the moon than a coin to me, so I'm going to give up on this one for now. Thanks for all of the help.
