A while back I posted asking if there was a white whale you had ever missed out on as I had missed out on a couple in 2023. Both of those haunted me in some way or another for quite a long stretch of time, particularly as I was fairly certain neither would show up again considering their rarity and scarcity. Combine that with my general lack of luck and I wrote them off until fate or something close intervened.
The gentleman who bought the 1909-11 S74 Zack Wheat Silk I missed out on had a second Wheat Silk he had purchased in an attempt to go after a complete Wheat run (there are colored and white silks to chase).
