1936 long Island Tercentenary so called dollar, HK694a - Help
Looking for some help here. I found this so called dollar from 1936 and am having trouble finding information about this particular one. I have found bronze ones online and the catalogue number is HK-694, however this one is not bronze but a white metal. There is apparently a variety in white metal (HK-694a) but I have not been able to find it anywhere. No pics, info on rarity, approx value, etc.
size: 33mm weight: 11.4g
I know this is probably a niche market, but does anyone have any info about what I have here? Thank you for the help!
