Glass Iridescent

how do you know if a marble is collectable?

I found some marbles and would like to gather as much information about them. Some marbles seem to carry a higher value and I am not sure why they do. Does anyone know how or what to look for in a vintage or older marble, compared to a newer one that might not have a lot of value.
thank you!
I didn't think so but this is the catagory that they assigned this question to. I have also posted it in another catagory as well. Thank you for your help.

The link has some picture of the type of marbles they are looking for, they appraise marbles VINTAGE AND ANTIQUE MARBLES ONLY...
TIPS
1. Stay away from anything that says "classic swirls";
2. Stay away from anything that says "classic Vitro's";
3. Stay away from anything that says "Jaybo Classics";
4. Stay away from items marked "huge lots" of 500, 600, 800, 1000;
5. No reserve auctions usually mean it's a worthless auction (unless they are a reputable Ebay seller) and also most times the item are damaged;
6. Do not bid on distorted pictures of marbles (out of focus, blurry, far away, marbles in jars, etc.);
7. Plastic wrapped lots that you can't see inside of, don't bid;
8. Anything claiming to be Indian painted, unless it comes with authentication, don't bid;
9. Anything egg shaped or crackled marbles, I wouldn't bid;
10. Any large lots of all the same color and pattern are usually new marbles;
12. Lots consisting of dull color marbles, don't bid;
13. Lots consisting of large amounts of clearies, don't bid;
14. Lots consisting of large amounts of colored clearies, don't bid;
15. Lots consisting of large amounts of single colored opaque solid colors, don't bid;
16. Marbles with pictures or with names that you haven't seen in any of the marble identification books are usually new;
17. Items marked "Chinese checkers" don't bid, unless that's what you want;
18. Any iridescent or oily surface looking marbles, don't bid, if it's a mixed bunch, and you see other older marbles, then it's your call;
19. Any mystery bags, or mystery packages, don't bid;
20. Remember, just because some marbles glow, does not mean they are old, don't bid if it's listed that way, companies such as Jaybo use old cullet glass with some uranium that they mix in with new glass. These will usually glow a weak orange or yellow;
21. Pictures with jars of marbles that are not displayed out of the jar, don't bid;
22. Any auctions with pictures that are dark and far away from the camera, don't bid or ask seller for better pictures.

Want to find out the value of your marbles? There are plenty of web information about all types of old marbles, especially in the Antique Marble and Price Guide, which also has information about the different companies that made marbles, and how they did it.
