Looking for help identifying and valuing 3 marbles

[sabbathz]

Recently picked these 3 marbles up at an antique flea market. I do not know a lot about marbles and I'm hoping someone can shed some light on them for me. Any help is greatly appreciated. They are all in good condition, with no visible signs of damage. They vary in size, I added a mercury dime for scale.

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

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

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