Now that 2022 had started, and I've entered (most of) my 2021 purchases into Numista, I can try to summarize my goals again...
1) Get some more missing dates for my OFEY
1a) In particular, fill in the remaining post-1720 holes (2022, 1844, 1781, 1756, 1755, 1729, 1727, 1723, 1722)
1b) Try to fill in the other post-1700 gaps as well (1719, 1716, 1714, 1712, 1711, 1709, 1708, 1705, 1702, 1701, 1700)
1c) If possible, try to get an unbroken line even further back (good luck, it gets really bad past 1700)
1d) Take some pics of the more recent dates for How Far Back Can We Go 7th edition... older dates too if it has time to get that far
2) Related to the above: get some (more?) dated Islamic coins from the 15th century AD
2a) Non-Islamic dated (and/or single-year-type) coins from the 15th century AD would be welcome, but unlikely to fit within my budget
2b) Dated coins from before the 15th century are useful as well, though I already have a bunch of those
3) Get to 400 issuers on Numista (currently 393)
3a) Extension: get to 400 issuers without notgeld (currently 374)
3b) If possible, also get to 250 countries (currently 240)
4) Get to 400 banknote issuers on Numista (currently 266)
4a) Alternate version: get to 200 banknote issuers without notgeld (currently 135, I think; I have a lot of notgeld)
4b) Also get to 150 banknote countries (currently 119)
5) Fill some of the remaining holes in my Dansco 7070 album
5a) In particular, get at least one more classic commemorative, and/or at least one more Seated Liberty silver
5b) If it shows up within my budget, get an Arrows & Rays quarter and/or half dollar, even though the 7070 doesn't have holes for them
5c) In theory, same for a CC mint coin (any denomination), but that's a long shot
6) Get at least one more coin for my Romanian type set attempt (...also figure out what exactly I still don't have)
6a) If I can find some Mongolian coins I didn't have yet, that would be cool as well
6b) Same applies to Icelandic and Israeli coins... I forgot what other countries I'm trying to do a type set for. Belgium?
7) Formalize my USSR non-commemorative type set progress, figure out what (if anything) I'm still missing, and get it (...discounting the gold, which is out of my budget, and probably never circulated anyway)
7a) If that turns out to be easier than expected, try the (base metal) commemoratives too
8) Formalize my Russian Empire AE type set, and fill at least some of the holes
8a) Some more of the silvers would be nice as well (AFAIK there are too many rare ones to do any type set work)
9) Formalize my 18th/19th century Swedish AE type set attempt, and fill at least some of the holes
9a) If my brief interest into those coins shows up again in 2022, do something similar with 19th and/or 20th century Portuguese coins
10) If prices manage to get back into a reasonable range, finally get a gold coin
10a) If I find any platinum within my budget, get that too
10b) Can I manage a non-MT thaler?
11) Add some more ancient coins to my collection, especially in areas where I'm still lacking
11a) Add at least one more of the first 17 Roman emperors (Julius Caesar to Marcus Aurelius)
11b) Add at least one more 5th century Roman emperor and/or empress (I already have most of the common ones so this will be hard)
11c) Finally get a 6th century BC coin
12) Get a coin from each decade up to 1500 (currently missing: 1680s, 1600s?, 1580s, 1540s, 1500s)
12a) Also figure out which decades I'm missing in the 15th and 14th centuries, and fix the gaps if possible
...there are probably others I couldn't think of at the moment, but I turned out to have a lot less time to write those than I expected, and the next one will be 13 anyway and I'm not sure I'm willing to end there. But if I'll think of some more I'll try to add them later.
(Crossed-out entries had been fulfilled in my first coin-buying expedition of 2022. The country and issuer counts do not include those purchases; they would probably change when I enter those into Numista, and I'm considering editing the new figures into this post at that time.)
