Notes:

[1] The Monochrome Proofs were done on thin card and in black and white by Walsall Security Printers of London UK, and were used to check the design.
The monochrome proofs were, usually, produced in amount of 20, then sent to Tonga for the officials to check. When accepted, they were sent to stamp magazines to illustrate the upcoming new issues.

[2] The Plate Proofs printed one sheet of plate proofs first, this sheet was taken for checking and approval by Walsall Security Printers company and the officials of Tonga.
After it passed the necessary checks, this imperforated proof sheet was placed in the printers archives and was left imperforated. All other sheets issued were perforated.
The Tongan plate proofs are genuine proofs done by the printers for checking purposes then kept until recently in the printers archives.
