hello everybody,

i want to sell my panda collection

do you know where i can find price cotation to have idea ?
i first compare ngc price guide and ebay prices but there is difference :/

eBay prices for sold items will give you an idea of the highest amount people are likely to pay. If you are making person-person sales the price will be less. Best wishes.
