Citing Atlas reefers as an example, those that would be seen logically in the region
I model, such as Coors, I'd run. Those from my home state with beer brands unlikely
to be seen in the mountain west, remain sealed in their boxes. Coincidentally, the
Coors cars and the other Colorado green beer reefer, are common, the home state ones are LHS short runs and WERE once pricey. I'd suspect their value has dropped.
For the Marx from my childhood, with some cars once very hard to find, with a
lot of trudging through train shows, after I discovered eBay, I found them all over
it, and not rare at all....although some are/were pricey.
