A Glitch Leaves Some Proof-set Cents Without A Mint Mark

Posted: September 09, 1990

Some buyers of the 1990 U.S. proof sets have received unexpected bonuses. The U.S. Mint has confirmed that it mistakenly sent out about 3,550 sets with a cent with no mint mark in the S-marked sets.

The error occurred because a Philadelphia circulation die (which has no mark) was included in the S-marked dies sent to San Francisco for production of the proof sets. The mistake was discovered, but not before about 3,550 sets were shipped to mint customers.

Harry Foreman, a Philadelphia coin dealer, said sets with the Philadelphia die cents, which originally sold for $11, are selling for as much as $1,500.

The mint sells two sets: the Prestige set with all circulating coins plus a proof specimen of the 1990 Eisenhower commemorative dollar, and the proof set of all the circulating coins. Both sets have been found to include the no-S cent.

The windfall has led dealers to caution buyers of the possibility of fraud - with a standard cent substituted for the no-S cent. Mint officials have urged buyers to examine the plastic cases in which the Prestige Sets are delivered to be sure that the seal has not been tampered with.

JERSEY COINS. Four gold and two silver proof coins marking the 50th anniversary of the Battle of Britain have been struck for the island of Jersey.

Four of the coins, the 100-pound and 25-pound gold proof and the 5-pound and 2-pound silver proof, show the Spitfire fighter over an outline of the British Isles. The design is by Ian Rank-Broadley. The 50-pound and 10-pound gold proofs bear Leslie Durban's design showing the Royal Air Force badge and motto, "Per Ardua Ad Astra" ("By Difficult Ways to the Stars"). Rafael Maklouf's portrait of Queen Elizabeth is on the obverse of all six.

The commemoratives are offered in a four-coin set of gold proofs at $1,595; the 5-pound silver proof (65mm diameter) at $145, and the 2-pound silver proof crown at $49.95. Queries go to the British Royal Mint, Box 2570, Woodside, N.Y. 11377.
