I, too, grab world crowns whenever possible/priced correctly. I especially like to grab Cuban pesos like yours just in case when Cuba really opens up, I hope there will be a big market demand increase from the native populations for pre-Castro coinage. And if not, that's ok, pre-Castro silver Cuban coins are nice to have anyways.
On a recent trip to Pittsburgh, PA, I got a nice Fine 1817 France 5 Francs for $25, which I thought was a good deal.
