I picked up a set of really nice May YH rallies with a mint set of vintage M&H slicks from a sYc member here on the site about a year or two ago. Slicks were mounted and think they were either $1000 for the pair or perhaps it was $1200 (was in that ballpark and they were really nice).
Shipping was the bigger challenge, but we got it done. Pics of the wheels w/ vintage slicks shown below. Hope that sets a baseline or helps you out.
