Vintage card regrets

[Ricky]

Long-time lurker, first time poster.

About ten years ago, I sold several vintage cards from my collection, probably 8 or 9 total, at a time when my daughter was going to college and we needed help paying for her tuition. Long story short, ten years down the road, even though it was the right thing to do at the time, I still regret parting with those cards, as I know that, with the way prices have soared in the past decade with vintage cards, I'll likely never be able to replace them.

I was wondering if other collectors had sold cards over the years that they now regret not having - and probably can't replace - and what those cards were.

For me, my top 3 that I sold and miss are:
• N172 Old Judge Hoss Radbourn
• N300 Mayo's Kid Nichols
• 1933 Goudey Ruth (red background)
