We can be fairly certain that no Tiger Woods collector has ever seen this flag, as we are unaware if another example has ever been sold. Offered here is an actual tournament-used pin flag from Tiger Woods' victory at the 1996 US Open, which has been autographed by Tiger.
This is the actual 10th hole flag from Pumpkin Ridge when a young Tiger Woods won the US Amateur for the 3rd consecutive year. It is beautifully autographed by Tiger.
