All shown, three ambrotypes (One 1/6, Two 1/9) and a 1/9 tintype with a 5-cent Civil War tax stamp on the back.
The 1/6 case has serious damage, the 1/9 plate case (bottom left, pic 2) is in very good antique condition with a loose pad, the other two cases are in good or better antique condition with some cracks. All of the cases have some degree of edge nicks/chips, mostly minor.
