The Fidelity USCF Special Edition followed the formula of previous Fidelity limited edition releases. Though this one was offered exclusively to members of the United States Chess Federation. An inspired way of getting rid of a few hundred spare Champion Sensory wooden housings and old Prestige chips at a premium price. The USCF was offered in a standard Champion box and with an Impact Printer.
They are rare, though one was offered on Ebay in January 2008.
My USCF SE reached me through an offer on a USA message board. It is in mint condition.
