Wow, very cool! I hadn't seen that before nor heard of the locale (Lampedusa or Lopadusa; maybe other spellings as well). It appears to be very rare.
I really like your crab, PMONNEY Maybe it's just me, but I like it when coin-folk use "Full Image" ... again, maybe it's just me?
My Lopadusa crab: There's a variety with double the crustaceous goodness; crab on both obverse and reverse.
