Welcome aboard! great choice with piazza! I'm a yankee fan also, but loved collecting piazza back in the day....I have the 1992 bowman set..also, I have a huge Griffey jr. collection....I pulled an '89 Griffey ud out of a pack on my b day ...still remember...still have the cards...I have a few '89 ud sets also..I used to collect "new" stuff years ago.....I crossed over and collect T206 exclusively....I'm 43 and have been collecting bb all my life(except the rebellious teen years
)...
T206 are the way to go.....email me or pm me any questions you may have....pick up a beater or 2 from ebay to get your feet wet
ps
you will love it here! warning- becomes very addicting
Peace
Johnny
