Ten types of  the  second  printing  have  thus far been identified. Only one of these types, however, is  known to occur in  all denominations. This  is by far the most  common type and  it may reasonably  be  presumed that this type, which is very similar to the type  of the first printing, is the type produced from the  first set of stones prepared for the second printing.

Each of  the remaining  nine types of  the  second printing  is known to occur in from two to eight of  the twenty-one denominations. Only one  type of the second printing  has been identified  for the  5c, 15c, 20c, 30c, 80c, 1.40p, 2.40p and 3.60p.  It is therefore assumed that only one stone was prepared for the second printing of each of these denominations, or that, if more than one stone was prepared, all stones were prepared by the same  artisan.  Two  types of the  60c and 15p have been identified, but one of these types is  the  same for  both denominations and  is the types which  is   common  to all denominations. It  is possible two stones each were prepared for the second printing of the  60c and 15p,  although  there is apparently no record of  more than one stone for the second printing of  each of those two denominations. Seven of  the ten known types of  the second printing are known  to occur only in those denominations for which more than one stone is said to have been prepared for the second printing. It is  therefore assumed  that these seven  types resulted from the  additional stones.

While  only ten variants  of  the second  printing showing sufficient divergence to be classified as separate types have been identified, there are many minor variations. As many as six minor varieties of a single type have been noted. It  is probable that there were fifty varieties of each denomination of the second printing for which only one stone was prepared, and that for other denominations of the second printing the number of  varieties was fifty multiplied by the  number of stones which were  used. But the differences between many of  these varieties are so slight that they cannot readily be distinguished. The  ten known types of  the second  printing  are described and  listed  in the catalogue which  follows.

The  series of  Giro  stamps which was  issued in 1900 was of the same design as the issue of 1699,  except  for the difference in date. These stamps were lithographed in the same manner as the issue of 1899 and  the stones appear to have been  prepared in the same lithographic establishment, probably from the same master designs as were used for the issue of 1899.

Hence, the occurrence of the  eleven known types of  the issue of 1900 may be explained in the same manner as the occurrence of  the eleven types of  the issue of 1899. Likewise the stones for the issue of 1900-1901 appear to have been prepared from the same master designs as the two preceding issues. The date is  omitted from the  issue of  1900-1901, however. The  occurrence of  eight known types in the issue of  1900-1901 may, therefore be explained in the same manner as the occurrence of the several types of the  two preceding issues. There is one  type which is common to all denominations of all three of these issues and this is the most common type of  every denomination.  It therefore seems probable that the same artisan prepared a complete set of stones for each of these three issues. The other types of each of  these issues are probably from stones prepared by other artisans. The several types of the issues of 1900 and 1900-1901 are described in the  catalogue which follows.

The  last series of Giro  stamps was  issued in  1902-03.  The design of this  series is very similar to  that of  the issue of 1900-1901, but the background  is shaded with  dots and  the stamps were printed from "halftone" electrotype plates instead of being lithographed. These stamps, like the  three preceding  issues, were printed in blue. The  issue of 1902-03 remained in use until the supply was exhausted and  specimens have been seen on original documents dated as late as January, 1905. The issues of1899  and of  1900 each consisted of the twenty-one denominations which had been authorized by the Royal Decree of May, 29, 1894. The  issue of 1901, according to Forbin consisted of  the following denominations: 5c, 15c, 20c, 30c, 60c.  80c, 1.20p, 1.40p, 1.80p,  2p, 2.40p, 3p, 3,60p, 4p and  5p. The writer  has not seen the 1.40p and 1.80p denominations and those two denominations were not listed by either Dr. Perry or  Mr. Kay.  Dr. Perry also does not  list the 5-pesos  denomination. Mr. Kay lists the 5-pesos  denomination but suggests that it may be a forgery because there is no 5-pesos value  given in the official list of the 1901 issue. The  writer has seen  a used  specimen of   this  5-pesos stamp and  believes it  is to be  genuine.  Dr.  Perry  states that 1.40p, 1.80p and higher peso values were not included in the issue of  1901 because sufficient quantities of these values of the  issues of 1899 and 1900 were still on hand. According to Dr. Perry, the  issue of 1901, without date, was  issued in December, 1900. [88] The  issue of 1902-03  according to Forbin, consisted of the twenty-one denominations authorized by the  Royal decree of May 29, 1894. The writer has seen all of these except the 9-pesos.  Dr. Perry  writing  on March  15, 1903,  listed only  ten denominations as issued up to that time, but stated that the remaining denominations would be issued as soon as required. The 9-pesos denomination had not been issued at the time Dr. Perry wrote. Mr. Kay listed the 9-pesos denomination in parenthesis apparently indicating that he had not seen this  denomination.

Effective January  1, 1905,  the Documentary  stamps,  created by the Internal Revenue Law of  1904,   replaced Giro  stamps  as  the means of paying  the stamp tax on  these documents to which Giro stamps had hitherto been affixed.  The  tariff  for  the  stamp tax on Documentos de Giro established by Royal  Decree of  May   29,1894,  had remained  in force without  change until repealed by  the  Internal  Revenue  Law of   1904. This  law, in  so  far  as  bills of  exchange were concerned,  did  not  become effective until January  1, 1905.  But  in October 1904,  in order  to  force the retirement  from circulation of  all Mexican and other Spanish-Philippine silver  currency,  the   Philippine Commission passed a  law which  imposed a progressively  increasing stamp   tax on all drafts and checks drawn  in the Spanish-Philippine   (Mexican)  currency.     The amount  of  the  tax was  increased each month from October, 1904f   until  January,   1905.  As a result  of  this law practically all of the Spanish-Philippines  currency had been  forced out of circulation by  the  end of  January  1905.  Thereafter   the  new Philippine peso  Conant)  whose  parity  was  fixed by  law at  two  pesos   for  one  dollar (U.S.  Currency),  became the  monetary unit of  the  Philippines.
