I believe the previous owner of the Tree and Mirror underwent an account transfer.

Collector's Tree has no other sales other than its last sale in full pure. Going with the last previous sale of 231 keys.

The Mirror also has no other sales. Going with the just barely outdated suggestion of ~49 keys.

1 key was recently priced at 1 key. So 200 keys would equal to about 200 keys.

The next day, it was turned into a Medi Gun.
