Thank you all so much! I found these marbles at a thrift store in Lansing Michigan. I saw a glass jar peeking out from behind the counter this past thursday, and it really caught my eye when i saw an array of colorful little spheres resting inside. The owner of the store and i have a nice rapport. When i asked if she would be willing to let me take a closer look at the contents of the Jar, she agreed and told me that she would be willing to part with a few. I had no way of determining the monetary value since I am not adequately educated or experienced enough on the subject. That's not what attracts me to collecting marbles anyway.. I choose the ones that i think are most aesthetically pleasing, or the ones that spark a memory, or inspire me artistically or in any other way. I am an artist by trade, i work with multiple mediums and enjoy creating and admiring all kinds of different artforms. In my opinion, Marbles are tiny pieces of art. Beautiful and unique, little spheres of history that can be held in our hands and passed on from one admirer to the next, or maybe kept close in safe keeping forever.... I will stop rambling now . I have several more marble that i didn't post because i didn't want to overwhelm or take advantage of the forum. i would be happy to post them if anyone is interested in taking a look? thank you again for your time, consideration, and wisdom.
