there is pretty much no limit on anything that you take out of the u.s (including currency exceeding $10,000 provided you declare it but that is for another thread(s) ) and that includes cigars but as the wise LessO2 points out below, remove the rings so not to encounter a power hungry screener (or put on fake rings if they are in fact cubans as possession of cuban cigars in the u.s. is against the law [tho that never stops me from having them in my humidor and smoking them ])
