The United States Mint has a policy to ship in-stock coins and products within 1 to 2 weeks of an order. However, "fulfillment issues" has resulted in delays on all orders for up to 4 to 5 weeks, according to a new advisory at the Mint’s online store.
Mint FAQ #218 indicates the issues causing the delays are expected to be resolved "soon," and that the Mint regrets the "inconvenience to our valued customers and appreciate their patience and understanding."
No doubt adding to the Mint’s shipping workload is the massive amount of individual orders for rolls of the new Lincoln Cent. From their launch on Thursday, May 14, to Sunday, May 17, the Mint sold 20 million Lincoln Rail Splitter cents, or 200,055 of the two-roll sets. With each penny weighing 2.5 grams, that is more than 110,000 lbs of pennies to ship.
While some collectors have already said they have cancelled their orders as a result of learning so many had been sold, the total number of sets the Mint will have to ship could be much higher by now with several extra days of sales since Sunday.
