I've always thought the black backs were a little tougher, being the first release. That being said, I dont think there is enough demand from master set collectors to increase the prices for either. Sans the sain/page error in the black back series.

There does seem to be a few reds and a few different blacks which are tougher to find. I'm wondering of they changed the position or style of the sheet between the runs, making different cards short printed? It could be that the big bulk lots usually have most of the low numbers removed anyhow, skewing the data.
