CardCow has been a leading online marketplace for vintage postcards for over 20 years. Our mission is to not only offer great cards for sale but also to preserve history as seen through postcards by providing an archive of historic images for research and discussion.
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 The CardCow Ebay Store (Ebay Listings), Amazon.com and Etsy.
Thousands of happy, repeat customers. Here are some independent CardCow Reviews & Feedback from Google Shopping, and Ebay feedback.CardCow Ratings with Google Shoppers are consistently 5 out of 5 stars:
