Thank you for the reply ,I will have my own pictures tomorrow afternoon, I’m going to the farm to meet the widow . These pictures are provided by the caretaker. Do these pictures offer any further insight ?

Good afternoon, grateful for any guidance & support . 
I have stumbled upon a 90 year old collection of marbles. Estimated @ 250000-500000k pieces . Widow desires to sell collection whole & intact . I joined this forum last night & my UV flashlight arrived this AM . Where do we begin ? Than you all in advance
