12 Rarest Stranger Things Funko Pop! Figures (And How Much They're Worth)
8. Halloween Billy
This debut figure of Billy, released in 2018 alongside the second season two's second wave of Funko Pop! figures, features the character wearing his leather jacket from the memorable Halloween party scene.
When it was first released, fans could purchase this Pop! for roughly $15 at retail, but since the season four premiere, the value has skyrocketed to between $80 and $95.
Similar to Max's standard season two Pop!, this Billy Hargrove figure has risen in value due to being discontinued. So, if fanatics want to get their hands on this Funko, they'll have to buy it from resellers, where the value will continuously creep up!
