According to the PriceCharting website, a collection of known original and major Independent cartridge games and hardware has a value of $4,406.60 and if all items are new-shrinkwrapped it is $18,408.14.
PriceCharting tends to be less than accurate and undervalued for all systems older than the NES, so Intellivision values are likely slightly higher for many items. YMMV!
