Added 5 Keys for a Strange Original(~16 Keys)

Low outlier, although it should be noted that the Original looks like it's spiking in price. So you might want to be careful if you see it being used in future sales for now.

I don't think any of these sales counter your 23 Key sale, so you could go with 23 flat for the time being.
