New Member Introduction

Retired, originally from Hawaii, now living in Las Vegas. New silver stacker as of
March this year. First purchases made at a local coin dealer. Just into Modern USA coins for now. I have submitted coins 3 times since May to NGC. No results yet. YouTube experts have "instructed" me that the $300 fees for grading that I paid may have been ill advised. If so, I'll chalk it up as tuition.
I joined PCGS, first, for an annual membership of $69.00. Tried 5 times to buy
supplies from PCGS online but my order would not cycle to the payment screen. I
called and they said they have a system problem. Two weeks !?
I joined NGC for $25.00.
Need a lot of tutoring from you.
Aloha and Mahalo
PS I have a Mercury dime that I need advice on. I'll post it, shortly.
