Brunswick 1963 Billard Ball Set very order rare

Product Name: Brunswick 1963 Billard Ball Set very order rare
This set is from 1963 Brunswick. They only made a few like this. Notice there's no circle or markings around the number's on each ball. They use to make balls from Ivory but I'm now expert on this. However they appear quite different than all the other brunswick years. Looking at the order balls they are discolored yellow but not from smoke. They also have lots of small bruises on them that stand out quite a bit. There in excellent condition. That's all I know about them. I bough them with the table and entire set up from 1963, sold everything but these and decided to go ahead and put them up for sale. Thanks for looking.
