The Collectors Society Pins doesn’t carry a very big demand.
They are extremely common since there are as many of them as there are the society gifts.
In 1998 as many as 24,222 were given out and In 1999, 27,648 were given out.
But if you are like me you keep your pins in with your society gift box, and would like a separate one to display.
Because of that collectors are looking for them and thus creating a small demand for them.
I would say value from $1 to $3.50
The 1995 of course would be the hardest one to find with a lot less made. My guess would be around 8,000
Maybe John has it written down somewhere.
Still a lot of pins.

Now the buttons are another story.
Some of them are very rare and one in particular has gone as high as $240 on ebay.
