"Bulk Lots" are groups of world coins that are deemed not valuable enough to sell individually (because the amount of work would outweigh any potential sales totals) and so they are sold by weight (usually, as @britannia40 said, by the pound.) The thing is, many coin shops either don't care or don't even make an attempt to look through their bulk world coins. You can find some great stuff in there.
60 some cents in exchange rate if you travel there. The Canadian is about $1.50 exchange if you travel there.
