The Microsoft Excel spreadsheet of basic PNC Catalog Numbers (at  http://www.USAstamps.com/references/PNC_Catalog/Numbering_System/Basic_PNC_Catalog_Numbers.xls) was updated on Dec. 30, 2003, with the following changes:

• Added F37psa-1111A to the "Flags" set of coil stamps.
• Added F37psa-S3333 to the "Flags" set of coil stamps.
• Added R37SE-V1111 to the "Regular" set of coil stamps.
• Added R37SE-V2111 to the "Regular" set of coil stamps.
• Added S10ATLAS-V11111 to the "Service-inscribed" set of coil stamps.
• Added S25AE[psa]-S3333333 to the "Service-inscribed" set of coil stamps.

These new PNC Catalog Numbers in the "Flags" set represent the recently found cylinder combinations (1111A) on the 37¢ USA Flag coil of 100 self-adhesive stamps produced by the Bureau of Engraving and Printing (BEP) and the cylinder combination (S3333) on the 37¢ USA Flag coil of 100 self-adhesive stamps produced by Sennett Security Products (SSP).

The new PNC Catalog Numbers in the "Regular" set are for combinations V1111 and V2111 for the 37¢ Snowy Egret coil of 100 self-adhesive stamps produced by Avery Dennison.  Rolls of stamps from R37SE-V1111 and  R37SE-V2111 exist with 10PV/10VP and 10VP/10PV.  The extended PNC Catalog Numbers for these varieties are as follows:

• R37SE-V1111<10PV/10VP>
• R37SE-V1111<10VP/10PV>
• R37SE-V2111<10PV/10VP>
• R37SE-V2111<10VP/10PV>

The new PNC Catalog Numbers in the "Service-inscribed" set are for combination S3333333 of the 25¢ American Eagle coil of 10,000 self-adhesive stamps with spaces produced by Sennett Security Products (SSP) and combination V11111 of the new Avery Dennison version of the 10¢ Atlas self-adhesive coil stamp with spaces from rolls of 10,000 stamps.
