After many years of collecting experience, any regrets?
Every collector can point to mistakes made. Buying that overgraded coin. Not learning to grade. Putting lots of money into fads that didn't last instead of sticking with the tried and true. Passing up that beautiful coin that you never saw again.
If you could start over again, what would you do different? Perhaps you would have specialized in a certain series from the beginning and learned as much about it as you could. Maybe you would have attended more shows, if you were able, or became more involved. Things happen, and maybe you couldn't be more involved with coins when real life got in the way.
I can never regret becoming involved with such a wonderful hobby that has brought joy to my life. But I may have done things different from what I did.
