Foreign currency

I love foreign currency. Which is why I love this website:
http://www.wearable-coins-and-clocks.com/newpage/FORpendants1.html

They've taken foreign coins and turned them into pendants!
I've tried similar things with the currency I've collected since I was little, but I'm too afraid to actually drill into them. O.o;; I don't want to break them!
And I don't like the way they come out after wire wrapping.

I'm eyeing that British Florin Elizabeth Pendant the most. Tudor roses for the win!
