10c orange (300,000)

If not stored properly, the 10c is prone to oxidation; the orange ink turns to brown and eventually to black.

1947 First Definitives issue

The first definitives of the Republic era were pictorials. These were issued as a set on different dates in 1947.

On March 23, the initial two values came out (10c, 20c), followed on June 19 by three (12c, 16c, 50c), and on August 1 by two more (4c, P1).

Quantities printed:
4c black Rizal Monument (140,000,000)
10c orange Bonifacio Monument (40,000,000)
12c blue Jones Bridge (12,000,000)
16c gray Santa Lucia (10,000,000)
20c brown Mayon Volcano (33,000,000)
50c green Colonnade of Palm Trees (9,000,000)
P1 violet Colonnade of Palm Trees (5,000,000)

Quantities for the 4c, 10c, 16c, 20c and 50c were reduced by later overprints, and in the case of the 16c by a further recall.

The 16-centavo value has a design error; it depicts Puerta Real, not Santa Lucia. Because of this, the remaining stocks of both the regular and O.B. overprinted stamps were withdrawn from sale on July 26, 1950.

Printing method: Engraved
Printers: American Bank Note Co.
Perforation measurement: 12
Unwatermarked paper

Possible shades of color in all 7 values.

Perforation freaks:
10c horizontal shifted downward
20c horizontal shift, vertical shift, vertical shift slanted to the right
The 20c and P1 have accordion flaws.

If not properly stored, the 10c is prone to oxidation; the orange ink turns to brown and eventually to black.

I have a hibrite paper variety of all seven values.
