Nice way to sock away that nest egg, @blewitt! This is what non-collectors will never understand about the hobby: they're worth nothing until they're worth something, and that can take five, ten, twenty, or even more years for that to happen. May fortune continue to smile upon you. :)
Domino's first appearance in New Mutants is a great example: it was a two buck book for years...until it was a $200 book. :)
Why thank you kind sir!! Yeah some want instant gratification. Some of these things take some time.
