In looking in Albert's book, your button would be one of the ones shown on page 394, number 12A to 12D. The button shown as being high dollar has a line inside the dots on the edge. In Albert's book, that would be 12A or 12D. In the picture you gave us I cannot tell in that inner line is present. In Albert' book he gives us the following: 12A has a border of 49 marks, 12B has a border with 54 marks, 12C has a border with 63 marks and 12D has a border of 72 marks. Now we need to count yours and the ones on the high dollar one. Good luck, I hope yours is the high dollar one.
You posted your picture while I was typing. I think you may have 12C with 63 marks on the border. I counted the ones Osage showed that was high dollar, and guess what, it had 63 also. But on yours I cannot make out the inner line, but it may be there.
