I have seen only two examples. In 1883, Honolulu put into use its first circle date stamp used exclusively for registered letters. Later strikes have clogged outer circles leaving the impression of a single outer line, sometimes mislabeled as 275.01. I have yet to see it on a registered cover or on any other standard usage. The words are oriented differently than in the genuine.
Letters are narrower and shaped differently.
Noted on overprinted high value stamps, as well as on low value overprinted stamps and stamps of the Republic Issue. No covers noted. This postmark is also noted in black as a receiving mark on inbound second class mail dated January 31, 1896. Tacoma, Washington also used registry marks on letters sent there. 79, p. 30-52, June, 1988.
