Who consigns in a major auction

In a major auction (i.e. Heritage Platinum Night, Stacks Rarities Night, etc), what percentage of coins are consigned by individual collectors as opposed to by dealers?

I'd guess most coins are from collectors. Maybe 1/3 from dealers.Dealers do not really stock big coins any more
