Quarter on wrong planchet, or what? 0

[Fitzz]

Got this 2002 Tennessee quarter which seems to be an error coin.  Much of the reverse fields and devices seem to be missing.  Is this an error coin, or what?

Not an error coin.  May have been given a home brewed science acid treatment by dropping acid on the reverse, which may have spilled over a bit effecting the obverse and exposing the copper core on the edge.

Similar to what's discussed at error-ref.com, but it doesn't appear to have been submerged.

Looks like someone was playing around and ground it down. Or it got stuck in a machine or something of that nature and encountered alot of friction that wore it down. Post mint damage.

Looks like it was thrown in some tumbler of sort tumbled it down pretty heavy or someone using small  polishing equipment

Unlike other aspects of Tennessee, your quarter is not an "error." It has been caught in machinery or deliberately altered. It is worth 25-cents provided you can get someone to accept it.

I am casting my vote for post mint damage.
