There are only 3 unpriced Vives (which are surprisingly not Halloween effects), this is one of them.

Only recent valid sale:

I was originally going to wait until my 2nd one sold to price this but the previous sale is getting old.

I'm going to set the low-end at the B/O of the one I'm currently selling. Hopefully that's fine. I've owned it for around 3 months and haven't changed the price too much until recently. I may or may not change my B/O later on. I quick-bought it for 37 keys.
