So I Came Across A Few Nice Riga Free City 1 Schilling Coins

Then you work on the next earlier type and the next later type, and all of the sudden, you've got an OFEY going.

Why?
The more you focus on varieties, the less you can work on dates.

But, OK, that's not my thing.

Actually, looking at some of those "alignment variants," this type was hammered. Though not unheard of, it's unusual for hammered coins of this size to have any standard alignment.

Anyhow ... it's a place with an interesting history. If I recall correctly, in the mid 1550s Sweden and Russia both had ambitions of taking over Livonia, so the Grand Master of the Livonian Order came to Sigismund August of Poland-Lithuania asking for protection. So Livonia became a fief first of Lithuania, then of the Polish-Lithuanian Commonwealth when it was formed around in 1570. Livonian coins of the 1580s-1620s have Polish rulers' names on them (Stefan Batory, SIgismund III). In the 30 Years' War, it was taken by Sweden, so if you continue your OFEY into the 1630s-1650s, you will find names like Christina and Gustavus Adolfus on the coins.
Russia takes over in the 18th century.

I haven't checked, but it's probably possible to get a majority of between about 1550 and 1650 via Livonia coins, without breaking the bank.

thanks for all that info tdz!
Where can I find information on The Haljak numbers?

Thanks for the explanations for the folks out there (it took me a while to get some of these memorized.

I am sure most don't care...but these coins are modern, not medieval.

But that doesn't mean it is correct. Do you think that the Medieval period lasted until 1600?
