Has anyone seen anything like this before? Is there any way to remove this? It is hard as metal, and may be.

That is bronze disease. It needs to be stopped.
NOW,
despite the damage already caused.
Google
'verdigris treatment' for some ways to do this.

Final treatment with Renwax is sometimes used.

Is there anything left under it? Can it actually be removed if soaked for long enough in sodium sesquicarbinate?

Is it BD? My understanding was that if it is solid it is encrustation, possibly with detail underneath.

Try soaking it in olive oil and than pick away at it. I think a lot of that crust can still be removed, hopefully there will be some of the design left underneath it.

I am with Chuy and Echizento. It looks like 'crud' to me.

A good (long) soaking in 'Demineralized Water' and picked at with a bamboo skewer, repeated many times, should help. (Olive oil is said to be quicker, but it will 'darken the coin.)

(Nice photos - good size and clear.)

I believe it is both ! Encrustation with BD attacking the coin. I had a nice sestertius of Caracalla that had some curious blobs of reddish encrustation (mostly on reverse). The primary question was whether to remove or allow to remain. The spots were not that large and I decided to put off a decision. About six months later I examined the coin and much to my alarm the neon green spots had appeared ! Happily they seemed to have a made a 'home' in the spots of oxidized encrustation on the reverse. The decision was quickly made a nd the 'stuff' was removed post haste !
I believe this coin will be saved too. The patina might lose some of its "venerable" look but the alternative is unacceptable !
IN GOD WE TRVST ....... all others pay cash !
