I am a new researcher of marbles and am looking to identify some of these marbles I have found in my mother's estate.  I have been researching, but all seems to be rather confusing.  I am asking if anyone can help confirm some of these marbles that I have found with the proper name.  And to you marble experts, can you provide any other identifying tricks I can use when searching for names?  Here are a few of my pics
