Best Place To Sell Short Domains(2-3 Letters)

Hey guys,

I managed to rope in a two-letter domain a while back, the shortest one I have ever owned.

Not a .com obviously but with a two-letter extension which makes it the shortest domain name anyone can ever own with just 4 letters in total.

But I was curious what's the best place to sell something like that?
I tried Sedo but not much hope there.

Domain name for curious souls: aa.md
