We all know value (price) is influenced by both condition and scarcity of an item.
With our experience with registries in the hobby, the value increases exponentially secondary to both these factors as well as the grade.
Let's say that there is a hypothetical rare item A worth $20000 in today's market and only two of them are known to exist.
Let's then say there is another very similar hypothetical item B worth $100000 in today's market and it is a true 1 of 1.
Let's also say that you own one of the two existing copies of item A.
Now an auction comes along and lo and behold the second item A has been consigned. The auction is almost over and a bid of $20000 has been made.
The world has been searched for decades and it is very unlikely that any more As or Bs are out there.
What do you do?
A) Go to bed
B) Place a bid of $21000 in the auction and raise it conservatively as needed until you have won the item. When you receive the item, you simply destroy it and consign your only existing item A in the next auction and wait for it to sell for around $100000.
If, my friend, you did not go to bed and answered B, I would suggest that you have turned the Collector's Nightmare into the Collector's Dream.
In other words, you will sleep better if you don't go to bed.
