This is from the U.S. Mint Website:

In the past there were "Born in the USA" Proof Sets with the **RD Product Code,


Also in the past Annual Dollar Sets were offered with an Uncirculated
ASE,

My guess is that this will be a Proof Set with a Philadelphia Mint Mark
ASE & Uncirculated Set from Philadelphia, unless Philadelphia starts making the Proof sets instead of San Francisco.

Only time will tell!
