NEWPORT BEACH, Calif. - Professional Stamp Experts (PSE) today announced that effective August 1, 2009 they will begin assigning a grade to U.S. Plate Blocks and Blocks of Four.

PSE President Michael Sherman noted "a great deal of time and study went into a methodology to ensure a fair and consistent grade that we could assign to blocks.  We will be placing a single grade on a block, not grades on the four (or six) individual stamps.  If and when the block is broken up, the stamps will need to be regraded as singles."

As a special introductory offer to kick off the new program, PSE will offer to add a grade to any plate block or block of four it has expertized in the past two years (certificate dated on or after August 1, 2007) for a flat fee of only $20.  This introductory offer expires Dec. 31, 2009.

Readers are invited to contact PSE with any questions or comments regarding the new service at 949-567-1346 or by writing them at P.O. Box 6170, Newport Beach, CA 92658.
