Slab Error, Worth More or Less? Updated W/ Photo

[silvereagle78]

I recently purchaced a slabbed coin, on the identification of it it says it is a D mintmark, the actual coin is a definate P. The mint mark shouldn't make a difference in the value, the reason the coin is slabbed is because it contains the designers signature on the tag. Would the slabbed coin be worth more or less because of their error? Thanks


Sorry I didn't include a picture with to start with.
