- 2 sellers at 21 keys

- 2 sellers at 23 keys

Quite alot unsold at 23 keys, quite a few at 22 and very few at 21 keys. Think a update is in order.

I chose not to include the 21 keys as there is not enough sellers atm, ill look for more proof and will close this and re-suggest with a better range if more 21 sellers pop up :)
