Prototype plaid Pac-Man Bandai Namco sleepwear pants?

[Armageddon Potato | 124]

I have just a few of these, and they apparently were never released. The tags are also have no information except the default Pac-Man tag as does the pants tag itself. I have a couple Super Mario Bros prototype clothes in my personal collection similar to this(but earlier in print with "Sample" printed on the tags.) Also they never have the default black elastic top and bottom part. Any idea on value for something like this? I'm assuming they didn't release them since no Pac-Man style clothing has plaid on it. Could of been an accident actually since this design actually goes on another style of sleep pant. These also have a larger version that has a button up shirt that goes with it. I'd snap a picture of those, but they are sealed in factory bags(They use the same design.)
