Yeah, it's funny when that happens. Had a couple of books like that too; a Detective 395 CGC 9.4 that I bought for $350 back in 2004-ish I sold for $1500 a couple of years later. Another was a JIM 109 CGC 9.2 I paid $650 for in 2002; sold it in 2005 for $1800. Books get on people's radars and all of a sudden explode.
Batman 227 is an odd one. It has gotten crazy in the last couple of years, and all based on the cover.
Yeah the price fluctuation kinda goes in circles. Like Tales of the Teen Titans #2, it spiked when Deathstroke was in Identity Crisis, then died back down and I'd imagine it's due again with his resurgence on the Arrow TV show. Yep, good'ole Neal Adams cover. The story isn't anything crazy, but I still love the book just for the Adams art.
