These include: a wonderful copy of The Amazing Spider-Man #1 (Marvel, 1963) graded 9.0 by the CGC and described by Heritage as "Easily the nicest copy of the milestone issue we've offered in nearly two years!"
Then there's Spidey's real first appearance with a copy of issue 15 of the ill-fated Amazing Fantasy series, which introduced the webslinger to the world.
But these are by no means the only highlights in Heritage's exciting sale. In fact whilst both of the issues mentioned continue to crawl up the price listings neither is currently in pole position for top lot.
That honour belongs to a restored copy of Action Comics #1, currently graded 8.0 by the CGC and carrying an $80,000 bid. Needless to say, Action Comics #1 introduced Superman to the world and an unrestored copy is the current world record holder for priciest comic at $1.5m.
Another comic which will no doubt be getting more attention following this week's extraordinary $343,000 sale is another copy of Captain America #1. This example is graded 4.5 rather than 9.2, but it is still likely to be benefitting from the hype surrounding the recent film.
However, it's not just comic books which are on offer. There is also a selection of Carl Barks's Disney Duck oil paintings from the famed Kerby Confer collection on offer.
Amongst these the greatest is probably Spoiling the Concert featuring a rapturous Scrooge McDuck playing his cash register like a musical instrument to the discomfort of Donald. His nephews are releasing mechanical mice into the gold and jewel strewn scene.
Currently holding a $65,000 bid, the piece is a true classic - not to mention a valuable asset given how highly regarded Barks's work is by collectors.
Heritage's auction takes place in Dallas, Texas on August 18.
