ATHENS, Dec 29 (Reuters) - Greece will sell 625 million euros ($692.13 million) of three-month Treasury bills on January 3, its debt agency PDMA said on Friday.

PDMA last sold three-month T-bills in November, priced to yield 3,88%. The settlement date of the new T-bills will be Jan. 5.

Only primary dealers will be allowed to participate and no commission will be paid. Primary dealers can submit non-competitive bids for up to an additional 30% of the auctioned amount, PDMA said.
