First try to sort your marbles by type and pattern. Don't sort by color. You should end up with the following major categories
1. Non glass marbles - Lots of subtypes but just group them all together for now.
2. Hand made marbles - These will all have one or more usually two pontil marks. Pontils are like pimples on opposite ends of the marbles. Once you see one or two they are not hard to identify.
3. Game marbles - all marbles with just one solid color, clear or opaque, are not collectable (rare exceptions).3
4. Catseyes - Clear marbles with colored glass inside. Some collectable but mostly not.
5. Baseballs - a distinctive pattern of 4 lines that look like a baseball.
6. Patch and ribbon - A patch on one end and a line around the equator.
7. Corkscrew - One line spirals from end to end without crossing.
8. Slags - White opaque glass inside a transparent color base.
9. Swirls - Everything that isn't one of the above.
There is a lot more to it than that, and each type has subtypes and sometimes named color combinations. Try to sort by marbles that look like they were produced by the same machine or process, in other words similar construction. After the initial sort, pick one of your colorful piles and post a picture here. We will help with breaking them down farther.
As far as remote location, how do you know one of your close neighbors is not a closet marble collector? Do they all know you have marbles?
