The cards use the 1983 template. They are chrome but have a different background than regular 1983 inserts from the 2018 set. The background did change between the two series and when you look at the cards you can easily tell the difference. There are 50 cards on the checklist for both series one and series two. Eight of the 100 cards are Cubs.
Ryno's rookie card was in the 1983 set, so we can compare the two.
