1¢ Green Coil 4UR10 A

Two guide dots at left centre - one touches the left side of the oval band while the other is just outside the left frame. There appears to be a third guide dot (under the cancel) in the upper left corner and there are several strong hairlines.

Research notes:

While not discussed in his book, Marler's personal collection had additional CPVs, often with multiple examples.In his collection, Marler had two, different, positions identified as coming from 4UR10. I have listed these as 4UR10 A and 4UR10 B. Hopefully examination of the proofs will help clarify.
Flaw in Zone 9
Plate Position: 4UR10
Not listed in Marler

We use Statser to measure basic website usage without cookies. The system processes page views, clicks, form submissions without form contents, referrers, browser/device information, error pages, approximate visit duration, and pseudonymous visitor keys. Full IP addresses are not stored permanently by Statser; they are processed briefly on the server to create a pseudonymous visitor key, apply technical exclusions, and optionally resolve approximate GeoIP information. If GeoIP is enabled, the IP address is checked locally against a MaxMind GeoLite2 database to determine the approximate country or city. The visitor IP address is not sent to MaxMind. MaxMind is contacted only to download and update the GeoLite2 database. Detailed data is deleted after the configured detail retention period. For long-term trends, Statser also stores aggregated daily values without individual visitor profiles.
