Vintage Jersey Appraisal

Is Siizuoka the name of the team on the front? If so, probably between $5 and $25, unless you fool unsuspecting people into believing that this is a pro jersey. I've chastised many a dealer for labeling "little league" jerseys incorrectly.

Can you provide the team name, player name, color, size, etc.?

"Siizuoka" looks like a form of "Shizuoka" which is the name of a prefecture (like a state). Names of prefectures are often on the uniforms of high schools for the bi-annual Koshien tournaments, usually on the sleave if not in the name of the team.

I think that only 14 players are allowed on the team at Koshien, with the best starting lineup numberd 1 through 9. Since a given pitcher can't pitch every game, I often have seen up to #12 in games. But I can't remember ever seeing any higher number than 12 at Koshien. (Admittingly, I don't watch that many high school games, but I do catch a few every spring and summer.) So even if it was the uniform to a winning team, it's highly unlikely that #13 played a major part. (There are exceptions, though.)

Kusumoto-san has done a great deal of historical research into not only Pro Yakyu, but college and high school ball as well. (He's got a great deal of diverse information many of you might be interested in.)
