Toy collectors are currently being invited to upload items for sale to a sophisticated and data-rich marketplace that is scheduled to open June 29. When it opens to buyers, the Toy Collector marketplace will primarily focus on buying and selling items in two of the most popular brands, Dinky and Corgi. The site's developer, Christian Braun, estimates that as many as 5,000 Dinky, Corgi, and other items will be up for sale on the opening date. Every few weeks, Toy Collector will add more brands for sale.
