It is very low, AO14AA and 42#. Now that I know that they may exist I will have to look for a Kodiak Special DeLuxe coinless to make it a set of four. I bought a really rough Special DeLuxe and refinished it. It is tough to do much with the clear glass but I did improve the hazing a bit. I would think that the 59 coinless would be easier to find since the coins didn't start until early 59.
