Hello,
I'm new here on atariage, because I need some advice.
I have bought in 2008 from Atari2600.com 2 Original Boulder Dash cartridges for the Atari 5200.
Yellow one with serial: 080 of 100
Red one with serial: 085 of 100
I have only opened the shippingbox they came in and never the games them self, so they are new and in the seal.
So I have the Original shippingbox and bill and email proof form JC Atari2600.com.
They are Original FSS release by Atari2600.com see year 2006 (https://firststarsoftware.com/boulderdash-htm/)
I only want to know what they are worth today?
Many thanks!
