5/8" and in NM - condition ( It has several Flea bites and scratches but displays well in hand ) by my eyes but look at the high definition pictures the size of a Baseball and you be the judge. 

Here is a super rare Peltier Slag in AQUA color which is a very hard to find and sought after color in these Peltier Slag's. It has a Feather + Fine-line Pattern. 100+ years old !
I do combine wins for discounted shipping for 3 days. I'll send you an invoice. I measure marbles through a drop through scale. I use my naked eye to grade. Considering the fact most are over 100 years old I do allow some slight imperfections. 

SPECIAL NOTE : I can no longer ship marbles in a Cardboard Box because of the increased cost. I will now ship in a padded envelope. UGH ! 

All identification is based on my collecting and experience over the past 50 years. I've always said you can show the same marble to four different collectors and have four different ID's and opinions. I do my best. BE ADVISED !!!  There are sellers that use misleading descriptions and buzz words for marbles like, Oxblood, Guinea and Submarine to increase the value of the marble. They simply add a disclaimer that they are not experts which is an easy outlet to mis-guide buyers. I've seen $1 marbles selling for $45. If you can, buy from an established dealer with a good reputation. Happy Marbling !!!  Rich

ALL MARBLES WILL BE SANITIZED BEFORE SHIPPING !

I BUY MARBLES FROM ONE TO HUNDREDS. IF YOU HAVE MARBLES YOU WANT TO SELL I WILL PAY A FAIR PRICE. PLEASE CONTACT ME THROUGH E BAY.
