CardCow has been a leading online dealer of vintage postcards for nearly 20 years.

We add thousands of new cards to our listings each week. Check our New Listings page, or create a Saved Search to get notified when new items that match your criteria are listed.

We buy old postcards.  We buy hundreds of thousands of postcards each year, ranging from small accumulations to large collections and estates.

Our current inventory of over 600,000 items is available on CardCow.com, but we also sell a small subset on Ebay and Amazon.

Thousands of happy, repeat customers.  Here are some independent CardCow Reviews & Feedback from Google Shopping, and Ebay feedback.
