Does anyone know if they will be releasing these Pres. coins on a quarterly schedule? Should John Adams be coming out in early April? I didn't see anything on the mint site.
Yep, the U.S. Mint website says May. Here's a link: http://catalog.usmint.gov/webapp/wcs/stores/servlet/ProdschedView?storeId=10001&catalogId=10001
May 18, last time I checked. For the business strikes anyway... they still haven't announced a specific date for the proofs yet. My guess is they'll be issuing the presidential coins basically quarterly, releasing the new ones in February, May, August, and November each year until the series is done.
