Marbles to keep an eye out for

[Spherophile]

I thought it might be interesting to compile a list of marbles to watch out for when digging through piles. Similar to how coin collectors will watch out for a 1944 Steel Wheat Cent (worth in excess of $100,000 so I hear). 
 

So what are some marbles that might seem ordinary but are actually worth get excited about? 
 

Here’s a few that some people are saying are hard to find but might not look too special:

- Ravenswood brown-based swirls with brown or red 

- Red glass mica

- Akro corkscrews larger than 1”

- Peltier with green pearlized patch

I always look for cross-through cat's eyes ... but those are still relatively common.

In the cat's eye category, the Vitros with 8 vanes appear to be considered special.
