Cranking up the brightness and contrast helps...


The word on the left side of the top pic is clearly "ARCHIDVC" - "Archduke". This is a key clue, because the only country that used the title "archduke" was Hapsburg Austria. So, this must be from Austro-Hungary or one of their other territories (like the Austrian Netherlands). The X-shaped cross also indicates Hapsburg Low Countries. The shield also looks Hapsburg, too. That helps narrow down the search.
On the bottom pic, we see remnants of the ruler's name: ALB...TVS ET ELIZA.... Searching Wikipedia for joint-rulers of the Low Countries, one of whom must have been "Elizabeth" or some variant thereof, and we find that
Archduke Albrecht of Austria and his wife Princess Elisabeth of Spain (a.k.a. Albert and Isabella) were joint rulers of the Hapsburg Netherlands from 1598 to 1621. Which matches your date "1611" nicely.
Coins in their name are perversely listed in the 1600's Krause under Spanish Netherlands (Austrian Rule) rather than Austrian Netherlands. The states of Brabant, Flanders and Tournai all feature these names, but the Duchy of Brabant liard of 1614 (KM# 24.2) is the only one pictured that looks similar to yours. As usual, pictures are pretty scarce for small coins of this time period.
What's the diameter of your coin? the picture of the liard is 23-24mm across.
