How much could I sell a Pokemon (First Movie) Comic signed by two of the leading voice actors?

I recently came into possession of a comic in excellent condition. This comic is of the Pokemon First Movie (Mew Vs Mewtwo) and is signed by the original voices of two of the movie (and the show itself's) leading voice actors of Brock and Meowth. The comic comes with a certificate of authenticity. Before I decide whether or not to sell it, I was wondering where would be best to try too? And for how much? eBay is a possibility, but I don't want to sell it for a lesser value. I don't want to visit my local comic book store, in case he undervalues the product and asks to purchase it for himself/his own collection/sell it on for more money. I don't expect it to be worth mega money, but I just want to make sure I know its value, as I've been told it could go for quite a bit in the right market? Thanks
