Gilded mini:

http://www.tf2outpost.com/trade/25084011 Sold+ MG Gilded (5.7) for Gifted Sunbeams Mining (mini at 10.35)

I suspect it was offered, 10.35 - 5.7 = 4.65 (rounding to 4.7)

There's a current B/O of 5, this seems alright, other sales were bulk for a PS Anger (Unpriced) and a Mega Strike Conga (used to update conga)

=10.35, using that.
