Brad is 100% correct. Keep buying them they will keep going up.
My little protest is I quit buying LE's at $25 face. I can do without them.
At this time I still take $10's depending on where they are from.
The bad part about $10's in Nevada is they have very little if any use on the tables. The FQ's did keep them on a $10 limit Pai Gow game. In other casinos like Arizona Charlies they are for us and a real concern to pit bosses when they hit the tables.
All chippers must make their own decissions on denominations collected.
I do not collect a chip, hoping it will go up in value. I collect what I collect because I am a collector. By the time I turn my collection over to my Grandson, I will not be around to care about its worth. Why should I care now? I just want to enjoy it.

Thats me and not everybody. the world revolves around everybody.

ONCE AGAIN - We deside the market. We deside the value to us.
Are large denomination LE's good for the hobby? I DO NOT KNOW.
History will tell us.
