[MCU] Was the original Captain America's shield as strong as the one he got later from Black Panther?

Given that Howard Stark had probably never worked vibranium before is it possible that he may have not been able to produce an optimum strength shield??

The double wrist mounted ones? They’re both Vibranium, no reason to assume one is better than the other. The Wakandan shields are better offensively, but caps shield is larger and can bounce. He’d probably prefer his own.
