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!

I cannot offer any help, but that is a nice specimen. Good luck with your search... Cheers, RickO
Neither PCGS nor ATS have a single specimen of HK-694a in their Census.
You should get it slabbed as the only one
If you do get it slabbed, make sure to get a TrueView or PhotoVision.
