1c-3c Official, "Sepcimen" Overprint Errors (01Sa, O2Sa, O25Sa two, O35Sa, O47Sa two, O57Sa, O58Sa, O59Sa two, O83Sa).
A comprehensive group of these rarities, all unused (no gum), rich colors, one 1c Post Office s.e. at left, 1c and 2c Agriculture thin spots, one 1c Justice tiny stain spot at bottom, otherwise Fine-Very Fine, scarce and valuable, a rare opportunity to acquire a group of "Sepcimen" errors, many of which are undervalued in Scott in our opinion, No. O25Sa with 1974 P.F. certificate
