I've never even heard of Griswold.
I guess it's hard to get behind a company that went out of buisness because of poor quality.
The original Griswold company did not produce anything of poor quality. The company, like many others, went out of business because it was acquired and thence poorly managed.
The Griswolds held in high esteem are the large logo products made at the Erie foundry before the acquisition. The small logo pans are somewhat less prized, and command lower prices.
Research shows that the older stuff is collectable, but I'm not willing to risk high $ for a counterfeit, or a later model sold as a "classic" (the cast iron version of "real clay").
If you researched poker chips that well, you'd be playing with 18 gram "casino-weight" brass.
Mine are all cross or large logo pans, with and without smoke rings. Each one of them was acquired for less than $80.
