Those look like the OEM Optional wheels for the "base" or DX model. If you look in the 1991 Honda CRX factory brochure there is a DX model with those optional wheels in 13". They wouldn't be for the Si because the Si uses 14". They are unique and uncommon. If you have the center caps, you could probably sell the set on eBay for a decent amount.
The 14" Si teardrop wheels are more common and desirable in my opinion, but some OEM only restorers may appreciate those.

That looks like them to me. Thanks a lot for the reply and all the info you included. I do have center caps and will likely sell them one day. Helps to know what they were for sure.
