SHAME ON ME!!
I have several of these coins.
How could I be so wrong.
This is what I know of mine:
1 liard
Liege
No date (1650-1688)
MAX. HEN. D. G. ARC. COL. (or variant).
Maximilianus Henricus dei gratia archiepiscopus Coloniae.

.EP. / .ET. PRIN. LEO. DVX. BVL (of variant).
episcopus et princeps Leodiensis dux Bulloniensis.

The ruler, Maximilian Hendrik (Henry or Heinrich), is from the House of Wittelsbach and therefor a cadet from Bavaria. He was Archbishop of Cologne and in his capacity Prince-Bishop of Liege.
