It also depends on who is local to you, if you have a good loacl market then cheaper ones sell better, if you need to ship everything then you would be better off with more expensive chalices since they are worth shipping.
If I would have only kept all of the chalice that I use to get a couple years ago. I had some amazing pieces and at the time not one person would pay a 1.00 an eye for them.
Back to the topic, like everyone has stated the only chalice that you will get a return on is the high dollar ones. But, they grow so slow that if you purchase a one eye frag now, once it is ready to frag the Chalice will most likely no longer be high end and in demand. But, you should still be able to get some of your investment from it.
