Absolutely fantastic collection of Spinfishers. I have never seen anyone display a full collection of these reels. They are really too new to be considered antique but they have very interesting historical significance.
In my opinion, your collection will have a great future in the collectible market. The Black 710 and 711 are already very sought after models.
Two other Penn spinning models that I believe will be highly sought after collectibles in the future will be the Models 747 and 757. They had a very short production run and in my opinion, they are great reels.
Congrats on a wonderful display.
