Tony Gwynn, very cognizant of his hit numbers recorded numbers 3030 and 3031 in this batting helmet, 9-3-99 against Florida. He put his signature in silver sharpie on the visor and wrote "9-3-99 vs. Fla 3030/3031" on the inside. #19 sticker on the back. Helmet is a Diamond Collection size 7 1/8. Shows great use.
