Snake Eyes was introduced in this book, the so-called Silent Issue. GI Joe 21 was a ground-breaking comic, without any dialog to distract from the visual story.
We see this book all the time at Sell My Comic Books.
It's NEVER nice. Sometimes, we get it in 9.0 to 9.2 shape, but copies in collections are never high grade.
Already a $1,000 book in CGC 9.8 and $500 in 9.6, we see a better bet in CGC 9.4. There is still upside, but your risk is lower.
It's a common book but lacking enough reasons for optimism to justify four figures, in my opinion. If you already own a 9.8, though, I'd hold it.
This is still a modern book. Don't buy anything lower than 9.0.
