Black border unglued?

[Deathseide]

Got a question I am trying to mull out, was there two printings of unglued that included a black border as well as a silver?
I have a plains that has the artwork and text of the unglued plains but has a black border instead of the displayed silver this database has.

From what I remember, all Un- basic lands were black border because they are just basic lands, and can be used in any set.
All non-basic lands were silver border to indicate that they were not tournament legal (outside of Un- tournaments).

Except that the un- card basic lands in this database are silver bordered

Yea in the data base it's gray but all Un-basic lands come black border so they can be used in tournaments. They were the first full art lands.
