Prior to 1954 U.S. Customs Court judges were not issued distinctive plates. It was only when Governor Thomas E. Dewey proposed in late 1952 that Federal District Court judges receive special recognition that their fellow judges asked to be included. The issue was first raised by Chief Judge Webster Oliver in July 1952 in a letter to the Commissioner of Motor Vehicles requesting USJ plates for Customs Court judges. His request was denied.
The matter was taken up by fellow Judge Paul Rao in a letter to Governor Dewey in December 1952. In it he makes the case that Customs Court judges are Federal judges, citing Title 28, Section 451 of the U.S. Code. If U.S.J. wasn't acceptable, the judge writes,
It seems to me that a way out of this difference of opinion suggests itself in the substitution of an alternative designation to wit, "U.S.C." (representing U.S. Court or U.S. Customs) ...
Governor Dewey wrote Judge Oliver in January 1953 offering to arrange for a JCC series. In Judge Oliver's lengthy reply, he reviews other judicial plates issued by New York State (USJ, JSC, JSS) and renews his case for inclusion with other Federal court judges. In June he renewed his appeal, offering to accept plates with a USCC or USC designation if USJ plates weren't available. He argued that those sporting JCC plates might be confused with city court, county court, court of claims or children's court judges.
That June Judge Oliver renewed his original request. Plates with the JCC designation, he argued, were too easily mistaken for those of other courts (County Court, City Court, Court of Claims, Children's Court).
The reply from the governor's executive assistant was unyielding. After having consulted with the Justice Department and the District Court, the governor was advised to keep the two series distinct.
In a November 1953 letter Judge Oliver agrees to the JCC series for himself and his three fellow Customs Court judges, beginning in 1954.
JCC-1 Webster Oliver (was CJ-3)
JCC-2 Jed Johnson
JCC-3 Paul Rao
JCC-4 Morgan Ford
One confusing aspect of the JCC assignment comes in 1954. In August of that year Governor Dewey wrote to at least one county judge offering the use of the same JCC series for county court judges. His offer was enthusiastically accepted. A typed list entitled "Issuance of 'JCC' plates for 1955 (JCC-1 thru JCC-120)" attests to this. The list does not give numerical assignments.
What happened to the Customs Court judges? Did they still get JCC plates after all? One other possibility is that they got their original wish for USJ plates. Yet there is no change in the number of USJ plates issued between 1953 and 1956. No other series are recorded through 1963 that suggest a Customs Court assignment.

In fact we don't have any evidence for Customs Court plates until 1973. Blue-on-orange plates with the prefix JUS and a registration number, like the one at left, were issued annually from at least 1973. Perhaps as early as 1980 the new uniform height dies first appears on these annual plates.
During the early 1980s most judge plate designs were replaced with a mixed silkscreened-embossed design. As far as we can tell, Customs Court plates continued to use the previous design, as the 1984 and 1985 plates suggest. The existence of a 1985 plate with the words U.S CUSTOMS / COURT at the left, followed by a diagonal JUS, all silkscreened, and the embossed registration, is a bit of a mystery: were both types produced for 1985? Which came first? Were both plates actually issued? I haven't seen a 1986 plate that would prove or disprove any of these conjectures.

In 1986 the Liberty base replaced the orange base and the design reverted to the previous JUS designation, without the separating hyphen. The embossed dates remained in the bottom corners. Beginning in 1990 plates were issued every two years. The embossed dates 90 and 91 appear in the bottom corners.
I have yet to see the Customs Court plates for either the Empire white or Empire gold base.
