About JSP Auctions

Who we are

JS Poulin and Son is a veteran-owned, family-run business established in 2023, specializing in estate liquidation. Over the years, we've had the privilege of helping numerous families navigate life's transitions with care, respect, and professionalism — turning the process of letting go into something manageable and meaningful.

In the winter of 2025, we launched our first online auction dedicated to sports cards and collectibles — an exciting new chapter inspired by our President, Seth, a lifelong sports fan and passionate card collector. What started as a natural extension of our estate work has grown into a dedicated platform for collectors and sellers alike.

At the heart of everything we do is family. Seth is joined by his wife Jessica, son Jacob, and daughter Julianna — each bringing their own unique strengths to the table. Together, we're committed to delivering an exceptional experience for both consignors and buyers, every single auction.

Whether you're looking to sell a single item or an entire collection we're here to help. Contact us today to learn how we can assist you.
