Agree on the 32/33 US Caramel as a nice pick. Also like 1921 or 26-29 exhibit pose. Or even a rare exhibit like the 1925 Champions one if you can find one.
Other than those maybe some other early issues. There's several poses in the 1922 E121-120 series that work. The 1921 E121-80 would be too pricey.
The 1922 W575-2 auto on shoulder series is another nice tough one. The National Caramel E220 is another great early one but would be out of range past a low grade 1 or authentic copy I'm afraid.
Good luck. I think rarer nice cards may be best bet for investment purposes but another idea may be a signed Ruth check.
