Nostomania Pricing Data
Nostomania pricing data is the most accurate in the world. How is it we can make this bold claim? Other pricing data providers base their pricing data strongly on "expert opinion". This expert opinion is often biased, resulting in unreliable and often inflated data points.
At Nostomania, we generate our own pricing data sets by processing actual sales information with our proprietary algorithms. We first generate a baseline data set of known items for a collectible category. We then set pricing data for these items based on actual sales, gathered from many independent, validated sources. The value of an item in the Nostomania database is driven by examples of what collectors like yourself have actually paid for that item.
How well does it work? Extremely well. Check out the following news articles for more info.
Certainly it is impossible for us to gather sales data for every known item in our database. In those cases where sales data is missing, we set and adjust values based on similar items in our database for which we have actual sales information.
With each site-wide update of our pricing data (currently quarterly), hundreds of thousands of actual sales are factored in to continually refine the data and keep it current. Nostomania is committed to providing collectors and dealers a service they can find nowhere else: accurate, unbiased, up-to-date pricing.
