I would be concerned about paying $500 for a recently signed Koufax for example. Who knows how that will look in 15 years?

Maybe if you focus on balls that have some age to them but still look good, you will have minimized the odds of self destruction.

The turn was not sudden, it did take time. They have reached a point where they are not deteriorating further but it was the first time it had happened to me.
