I expect it'll be quite soft and full of flare.
It may surprise you. My sharpest lens is an uncoated 12" Goerz Dagor, made in 1911. It has slight flare, and in some situations has provided beautiful shadow tonality that would've been lost had I used a coated lens, such as my APO Red Dot Artar or my Nikkor.
