I have been collecting marbles for about 15 years. I have no idea what I am doing just gravitate to the interesting ones. I think I know what some are but I am constantly second guessing myself. I am going to try to take pics but my macro lens is not working all that great so need to bite the bullet and spend money on a new one then I may bombard with pics. Any suggestions on best forum to post for help?
