[Aquarian Sports Cards]

Usually the submitter can provide enough information (not just their own say so, but actual evidence) about the set.

I had a fight with them over the only known (at the time unknown) 1909 Rose Postcard Cy Young. It had the sticker covering the team name as he was traded between 1908 and 1909. There are several known players who were also traded in that time frame who had the sticker variation already accepted by PSA, but they called mine "altered" I had to provide all of the articles and information about the sticker variations and convince them that the hobby knew a Cy Young variation SHOULD exist, it just hadn't been discovered until now.

They went through the material I provided and ultimately acquiesced and put a number on it.

Slightly different case for an unknown card, but a similar process I'm sure.
