About 1 BY
Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The BY index mark traces back to Croydon, now associated with London. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 3 characters, 1 BY sits in a very short collector tier.
