eBay

No real value  Still being sold for around a buck 

The first looks like it may be an Akro Agate corkscrew with little cork, Called a lazy cork, No idea on the second . The pics will be better if you put the marble on a non reflective surface. Gray cotton tshirt type material works very well

hard to tell what the first is but it would not have much value.

Looks to be a Contemporay Handmade 10-20 dollar possibly more depending on maker

Vacor Neptune made in Mexico. No real value. Often confused foe vintage slags
