I don't know if there's a general, current going rate for Loyalty Points, but based on the items released at the same time, they're priced anywhere from 1.6m to 2.6m per point (which would put it around 30-50m). The other 19-point items are currently priced between 15-25m right now.
So depending on how fast of a sale you're looking for, you could start it at 40-50m and see if it sells, or just shoot for 25-30m and try to get rid of it faster
