I've been a collector for decades, and have seen the hobby go through many changes. Some good, others not so much.
One of the things that bothers me is how fast signatures of recently deceased appear for sale. Sometimes within minutes of the announcement.
I well understand the motives, competitive factor and psychology why this happens. But I find it crass, insensitive and disrespectful. Currently Betty White is an example. It was utterly insane when Kobe Bryant passed away. And in almost every instance of a well known figure this happens.
To me, it reveals that the collector has no interest or attachment to the memorabilia of the deceased. Things are just merchandise, alive or dead. Which I do recognize as a an element of the business side of things. But please, at least wait till the body is cold before trying to cash in on knee jerk reflex reaction.
As well, fakes and fraud are often more likely at such times when emotional instinct is highest. Market value always increases with death, but is it so cut throat a hobby/business that a day or two can't go by before rushing out over priced items?
