If Jeff's lone 9.8 went for sale and it made it's way to one of the BIG Auction Houses, they would advertise and market it to the utmost and I think it would EASILY surpass many expectations on the final price. (I know, I'd be bidding like a Mo Fo on it!) As for the Turtlemania Gold....I think that could go either way. Personally, I think it might pale in comparison to theTMNT #1 9.8. It just doesn't have the clout.
I feel that with Heritage's database and connections, they did a stellar job reaching out publicly and possibly personally, to people who might not be aware of these books and their value. Moreover, their true significance to the Turtles, the Turtles in comics, to the Comic Industry, the Independent Comic Industry, historically upon the Copper Age and just the simple fact of such a low print run.
I congratulate the buyer, I'm jealous, they sure are a purdy pair, I would love em.
Just to clear things up. TMNT #1 (CGC 9.8) would be close to the figures for Goobledygook #1, maybe a little more. Turtlemania Gold and Miracleman 3D-2D version (CGC 9.8) would be close to the figures for Gobbledygook #2. As stated earlier in this thread a Turtlemania Gold as already sold privately for $4000+. Sorry for the confusion.
Congratulations to the new owner.
