I urge you to occasionally sell some of your coins—you will become a wiser, more educated collector. [You may also avoid unpleasant surprises when you do decide to sell some or all of your collection.]
Learn from my own story…I started collecting coins as a child. Like most new collectors, my method was a trip to the bank to get rolls of Lincoln cents to search for better dates to put in my Whitman blue book. It was a really fun treasure hunt. I was buying valuable coins at face value! But I did not sell any.
