Market Values & The "Mint in Box" Rule
Vintage diecast valuation is ruthlessly tied to condition. A model with heavy "play wear" (chipped paint, bent axles) is often worth mere fractions of the same model in "Mint in Box" (MIB) condition.
Original packaging is paramount. In many auctions for early 1960s Matchbox models, the crisp cardboard box can account for up to 60% of the total realized price.
