Hot Wheels Mid-Tier
Mid-Tier sits above Mainline retail (about $2.00 to $6.00 for 1:64). Packaging is often still a peg card. The line name belongs in Series — never write Silver Series or Color Shifters into Category.
Category Rule
On SmartWheelers, Category is the price tier only. Named product lines belong in Series (and Sub Series when needed), not Category.
Series Under Mid-Tier
Silver Series; Color Shifters; Color Reveal; Neon Speeders; Vintage Racing; Ultra Hots (when Mid-Tier retail); The Hot Ones (when Mid-Tier retail); Flying Customs
