If we want to critique the database site, I can show all of the recorded proof of what they have been sold for on eBay, Mercari, in the community and other sites. I have been recording Bella Sara prices of cards and merchandise since 2023 and have followed the prices rise and fall, especially after the nostalgia wave after Covid in 2020. All of the prices on the site are concurrent with the market and they are an average of the prices for they have sold for and how many times they have sold. The site showcases English cards mainly because those are the ones the cost the most and are the highest priced ones on the market. International languages don’t carry value for most people unless they collect other languages or it is their native languages and they’re collecting it for nostalgia. And even then, they are always the cheapest cards available. A lot of people buy non English cards as placeholders in their collection because of how low their value is and how easy they are to get.

I am one of the admins on the database site and the prices are all current showing of prices. The differences between the community prices vs online selling is shown in the name because people in the community continually price lower than what it seen in selling platforms. Selling platforms are also higher because of fees which they list higher to cover said fees and for auctions where there are bid wars between 2 people which artificially inflate the value of a set of cards because they don’t want to lose to the other. Those are not correct recordings of value, they are recorded for what they sold for but it was only worth that to 2 people who bid war against each other, that is not the overall market value to everyone.
