When General bought Torano in 2014, they discontinued several blends. Last year General reintroduced the Casa Torano, the Gold 1959, and the Gold 1959 50 years. These new 2018 releases have the "legacy" band to differentiate them from the old Torano stock.
So in other words, the Gold 1959s you have been smoking have been old, Carlos Torano blended cigars. The new ones you recently received are General's interpretation of the blend.
