About Hip eCommerce

The Best Collectibles Marketplaces

Built from the ground-up for collectibles

We run marketplaces and communities built from the ground up for specific collectibles.

Within our marketplaces, hundreds of thousands of people around the world connect, to buy, sell and collect collectibles. Within each of our marketplaces, you’ll find services built from the ground up to serve the needs of each collectible buyer and seller. For example, our custom built search engine on HipStamp intuitively understands County and Catalog Number searches to provide collectors with unmatched accurate and relevant results to help them find exactly what they’re looking for. We also offer a wide range of Seller Services and tools to help sellers of collectibles reach a wider audience, and increase their monthly sales each month.

Our Mission

To re-imagine eCommerce for collectibles - by building collectible specific communities where buyers and sellers can connect with each other, share their passion, and grow their hobby.

Vision
