Tough call here. I have paid bigger dollars than this for the Hard Hero Chrome Silver Surfer (it was the the only one made in chrome of the 500 pieces, and numbered edition #48, first appearance number). For me it was worth getting. I know for others they would just shake there heads at the price I paid for it.
But a year later, I was able to purchase edition #49, the first cover appearance and painted version of it, and have the #48 comic, grade 9.4. And the #48 chrome is signed by Stan Lee.
At the time, I was thinking myself I was over the top, when I had the #48 chrome Silver Surfer. Looking at how this collection has come together, and how I will display it, I think it was worthwhile, first and foremost from a collectors point of view, and yes, financially.
I looked at the auction description. New condition, never displayed, includes the shipping box which appears to be in good condition. Would I have paid that price? No, because I do not have an interest there in the dioramas. If I had a strong interest in it? Maybe not, unless I was looking for one in NEW condition. The edition size is big enough though that you may find one new cheaper.
