So many beautiful coins! And that Aachen groschen looks fragile.

...and I almost missed that but we just passed through another AH/AD date conversion snag - 1406 AD corresponds to 809 AH, but 1405 AD apparently corresponds to both 807 AH and (just barely) 808 AH. Both of those AD years got very clearly covered, though.

Current gap listing: 1464, 1463, 1462, 1457, 1454, 1446, 1428, 1426, 1414, 1409, 1408, 1407, and I think no further gaps are expected for a while yet but we'll see. AFAIK I don't have anything until 1387 (789 AH).

I had a good day at auctions today and picked up a 1426 AH 829 Timurid tankah, and also a 1428 AH 831 Gujarat half falus. I'll do a catch up once they arrive down under.
Looking forward to it!


On my own end it's still unclear whether, and/or when, I would be visiting Moscow, but for now it's more likely than not, and two of the big items on the to-do list there are 1) taking pics of as many of the coins I left there as I could, and 2) trying to get a few more coins for my collection from various Moscow coin stores.

So if things go well, in a few weeks there should be a wave of coin ID threads on the Ancients subforum, hopefully followed by a (smaller) wave of catch-up posts on this thread as I finally photograph and/or identify some of the yet-unposted 16th, 15th, and 14th century coins in my collection.

I must be slow on the uptake @j1m. From my converter, I see that there are 186 days of 1405 within the AH year of 807. Conversely, there are 178 days of 1405 within the AH year of 808.

Of the two AH years, 808 is, to me, the troublesome one (178 days in 1405 and 176 days in 1406).
Is my math wrong, is my calendar off the mark, or am I missing an important point?

That will be very interesting @j1m. Looking forward to seeing some new and interesting items!

Your math looks pretty much correct, your calendar looks right on the mark (assuming Gregorian, anyway), and this is pretty much what I got - 807 is unambiguously 1405, and 808 is troublesome but if we had to choose one AD year to convert it to then 1405 fits slightly better.

I'm not sure what you're missing here. To me it sounds like you agree with me exactly but (I'm guessing) had probably misunderstood some part of my description as saying something that I didn't actually intend it to mean.

Hopefully it all works out eventually.

No, all good now. I mis-read your reply, without taking time to study what you said. I am glad to hear that our converters seem to line up too.

Onwards!

We are definitely getting near to the end of my mostly continuous run of dated/datable coins. I have a few in the 14th Century I think, but this Groschen from Aachen dated 1403 AD is my last for a while. I have attributed it as Levinson I-6, but am a little bummed about the huge chunk of the coin missing. These don't seem to come up for auction too often though.

I like the quirky coins with "issues"..... to me, the coin is what it is, and the chunky bite taken out just adds a certain character to it....

Excellent coins so far!

I wonder what's up with the weird conical holes; they look post-mint. My guess would be test cuts, but if so there's rather a lot of them. Fortunately they don't really mess up the design.


"Final" gap listing for the 16th and 15th centuries, pending possible catch-up posts: 1464, 1463, 1462, 1457, 1454, 1446, 1428, 1426, 1414, 1409, 1408, 1407. That's 12 gaps, or, in other words, exactly 94% coverage.
I believe this number might actually trend upward for a while due to less dependency on datable coins for the 14th century in the How Far Back threads (...mostly on account of there being fewer good examples of those in the first place). Past 1350, though, things might get interesting.

(I think I estimated at some point that there's a good chance we wouldn't get below 90% coverage until we reach the 13th century; this definitely seems fairly likely at this point. I wonder if we ever end up dipping under 50% before we reach BC dates.)
