What a great find - congrats!
I agree with Party that with his accessories he should be around the $30-35 mark. An accessory is no different from a pony, if its got staining or damage it will effect value - and unfortunately someone will likely be unwilling to pay the same price for something with damage as they would for something they could purchase with no issues. However, I do think it only brings the price down a tiny amount perhaps $25-28
The hat could be a factory bleed issue when printing or staining from something completely unrelated that the hat was pressed against or exposed to - but the almost identical colour from the print suggests factory.
