The 8R from invoice 10, and the ½R from invoice 67 are not known to exist. The 4R and 8R stamps from invoice 67 are only known unused.

Returns of the ½R stamps appear to have included stamps from several earlier invoices, therefore making it impossible to accurately estimate how many from invoice 10 1866 were sold.

Cerro Gordo received an estimated 100 ½R stamps, sub 13 1866 on 10 1866, while Penon Blanco received an estimated 100 ½R stamps, sub 19 1866 on 67 1866. These were the only two shipments of ½R stamps to any sub-office in the fifth period.
