On the 23rd June 1898 Emilio Aguinaldo declared Philippine independence from Spain and became the president of the First Philippine Republic. Shortly after, the Revolutionary Government released a number of postage stamps, revenue stamps and stamped paper. A lot more detail is provided in History of Philippine Revenue Stamps (Revolutionary Government (1898-1901). In all 10 stamps and 8 pieces of stamped paper were released. Of the 10 stamps, only 2 were dedicated to postage and a 3rd was a dual purpose telegraphic revenue and postage stamp (top row of the image below). For completeness I have also included all of the revenue stamps in this section.
Note: many of the revenue stamps from this era do not have Scott catalog numbers.
Scott #’s:
- Postage stamps of the Revolutionary Government (PH Y1, Y2, Y3 with Y3 being a dual purpose revenue and postage stamp)
- “Telegrafos” – Telegraphic revenue stamps (Scott unlisted)
- “Impressos” – Newspaper tax revenue stamps (PH YP1, YP1a)
- “Recibos” – Revenue stamp for taxes on receipts (Scott unlisted)
- “Certificado” – Revenue stamp for taxes on certificates (PH YF1)
- “Trans de Ganados” – Revenue stamp for transfer of large cattle (Scott unlisted)
PH Y1 is by far the most expensive and hardest to find with a low production rate of only 1,500 stamps. Similarly, but not as scarce is Y3 with only 10,000 stamps being issued. The cattle stamps can be a challenge but are not as scarce as Y1 and Y3. More information is available on these stamps here.
