Some years ago, I attended a World's Fair of Money that featured many special exhibits. Besides the usual array of wonderful collector exhibits, some coins that weren't seen often were displayed. This was the show where the ten 1933 double eagles were shown. There were long lines to see these coins from the time I walked in the door.
The show was in Denver. One special coin displayed was the rarest coin with the Denver mintmark, the 1927-D double eagle. The mintage figure was healthy, but nearly all were melted. Only a dozen or so still exist.
This was a few years before my own research into the survival rates of the "later date" double eagles, but I realized this coin was special.
Among the crowds at this busy convention, collectors and dealers, coin lovers, I made my way to see the coin. I was the only one near it. No lines. Just me.
I got up close and got a good look at that special coin, one of a dozen or so, and I knew how important the coin was and how lucky I was to see it.
That was one of the highlights of that show.
