Whose So-Called Dollar collection was sold by Heritage tonight?

Zoins

In tonight's Heritage Weekly Online Auction there was a nice So-Called Dollar collection with some rare pieces. Heritage didn't have any descriptions for these lots and, while rare, the slabs didn't have provenance / pedigree listed.

Anyone know whose collection this was?

Did anyone bid or win any?

I bid on 5 medals and won 3.
