HELP: MLB Debut Cards

[XZYXZY]

I need some help regarding the 2016 Topps MLB Debut set.
From what I can tell, there are four versions of this card.
Hobby has gold, silver & Bronze while retail has copper.
Is this correct??

Checklist here says retail only with gold and silver parallels

Gold, Bronze, and Copper, and I can't tell the difference I guess. Kinda like back when Bowman Heritage had the whites, unless you had all the versions, you didn't know what one it was.

Bronze versions are in blasters, silver in retail cello packs, gold in hanger boxes.
