Any document presented for assessment of stamp duty had stamps affixed to it for the full amount. Any subsequent document relating to the same transaction had Denoting stamps affixed as proof that it concerned the same transaction.
Occasionally a stamp other than an officially overprinted one was used for denoting duty. In these cased the word DENOTING was written across the stamp, and its use was confirmed by the initials of the Stamp Duties Office clerk. Such examples are very rare and should be collected on document proving their use as they could easily be created.
