Ok - how about a single card?
Topps did an online exclusive all blue sapphire Chrome set. The full series 1 and 2 sets. That's how I have a Chrome Eaton from 2016, as he & most of the Sox got kicked from the hobby/retail Chrome set. For $5.75 total with shipping, I could have bought a pack of Chrome and not pulled ANY Eaton cards, so this is a win in my book. And the scan does these cards zero justice. These are gorgeous in hand.
