You know, it's not always the item that makes it antique. If it's old then it might be an antique but it has to have some symbols or words on it.

An antique is anything that is 100 yrs old or older. There are some "antique" marbles but there are different characteristics that make a marble collectible and it takes someone who knows about marbles to be able to tell you if your marble is antique, collectible or both and the value of the marble.
glass, marble, or limestone.

Marble, CaCO3 will not usually scratch glass, but maybe a very soft glass. Marble has a hardness of 3 to 4, whereas glass is 4.5 to 6. (in a relative hardness scale.)
well, if its crystal clear glass, then its a very valuable antique. if its heavy, its probably not that great.

There is not a definitive value for antique red glass. There are not only differing prices for when the glass was created, but what shade of red they are, such as ruby or cranberry.

What size marble? And is it made of marble or glass?
No. A marble is made of glass, not marble. Glass will not react with vinegar. Edit - Some antique marbles ARE crafted out of marble or other stone/ rock types. Using ANY sort of chemical to clean them can possibly damage the surface finish or even worse, cause the marble to break or split. I happen to own a few antique marbles from the 1880's to the early 1900's. To clean them use a damp, warm soft cloth. Try checking each marble by carefully rubbing a small portion of a marble before cleaning the entire marble(some marbles are sun hardened clay, and getting one wet can damage them). One other method to identify the material your marble(s) are made out of - try a local rock shop. Most rock shop owners can identify what your marble is made from, if it is a naturally occurring rock. They might even be able to provide the possible value of your marble(s), but you should ALWAYS get a second opinion for any value appraisals.
