This just landed in my mailbox: I'm assuming this gold issue will be the same undersized, not-even-full-bands disappointment as the 2016 issue, but I wonder...
Link to details of the first commemorative gold coin and silver medal: https://www.usmint.gov/coins/coin-programs/semiquincentennial/ I'm not a medal collector, but this design really catches my eye. (Clever link between obverse and reverse, making everybody want to buy them in pairs...)
If it's 1/10oz, with spot value at $3337, bet it'll be more than $400. Of course, by that time world peace will surely have broken out and gold will be back down under $2000, so maybe I'm wrong.
