Thank you very much for all of your informative replies on & off
list. Some of them were so chock full of info that I printed them out
to share w/Dad. Hopefully he will see that he is the only one that
thinks Opal rough is worth spending lots of $ on.
I will check out Gold/Silver Coins/etc. when the price comes down
some. It just looked like it was on the way up w/no retreat!
Thanks again to the graet Orchid community & to the folks behind the
scene that make it all happen.
