I would agree with many that there will always be more demand on the Cobb side. Because it's from the most collected pre war set ever and is the most wanted of the 4 Cobbs. It's colorful and has been a blue chip classic card forever! The demand will always outpace the Ruth black and white exhibit. However when considering which is a better investment you have to take the supply part of it into the equation. That's where the Ruth is the clear winner. The supply part of the equation is not remotely close. There is a very adequate supply of Cobbs with the Ruth exhibit exponentially smaller in supply. So the best investment boils down to if the Ruth demand, albeit much smaller than the colorful Cobb classic, can outpace the much more limited supply?
It takes much less demand uptick and fewer sales to move the Ruth price.
Tough call. I'm happy I have both
