looked at several quite similar on ebay,UK that also lists these as celluloid early to mid 1900`s,, just not sure how correct that is !! also one that had a shell shaped one like the two you have that says carved oxbone !! so you may have two types !! neither was particularly expensive,, little over $10. ea. i would say that is about right,, but the boat,, go a little more !! might be a hard sell though !! collectability is the key to how well they will sell !!
