I consolidated my ha.com search to
US coins and "lamination" only then filtered the description to show proof under "coin finish" sub menu, this time I was returned 36 items in past auctions. Some really neat looking coins that have been sold over the years. Many patterns, more than I would have thought, maybe this says something about not taking as much care when working on coins not going to the public, but being used around the mint as show pieces for what engravers and apprentices could produce. (guessing anyways).
Sale#1219 CSNS 2015 Lot #8987 a 1776-1976-S 50C Silver Proof
Kennedy half dollar w/ Reverse Lamination NGC PR64 Cameo is one of my favorites, spectacular for an error proof. It sold cheap IMO too! @ $493.50 I know it's not exactly what I collect nor classic but WOW. Many of the laminations on proof coins are small or around the rim from the few I've found looking around now. Definitely proof laminations are an interesting type of error and worthy of collecting.
