Wow, Joel! Great work.

I have 4 examples that may be of interest to you:

1. Rickey Henderson Blue Jays cap from 1993. As you know, he only played half of a season with the Jays, so this example can specifically be attributed to 1993. I have a MOS certificate for this, so provenance is excellent.

2. Dave Winfiedl cap from 1992. He only played once season with the Jays in 1992, so this can also be attributed to a specific year.

3. Jesse Barfield 1989 cap. The reason why I was able to date this cap was because this is the first year that the Jays wore the navy blue caps as road caps. As you know, Barfield was traded mid-season, so the only option would be if he wore it in 1989. I had Barfied personally inspect this cap when I met him a few weeks ago -- so I am confident in its provenance.

4. Shannon Stewart 2000-2001 cap. The only reason why I was able to date it was because it came with a cert from Authentic Sports Investments, and was dated in late 2001. The Jays only started wearing this style of alternate cap in 2000, so the only possibility is 2000-2001.

I have a few spring training caps, no sure whether or not they will be useful to you. Looking at what you've compiled, all tagging matches up with my examples. The only question mark is my 1992 Winfield example.

Please let me know what you think. I can provide additional photos of the inner tagging, if necessary.
