Auction vs Fixed Price on eBay: Choosing the Right Strategy for Your Postcards

If you sell postcards on eBay, one of the most important decisions you can make is choosing between an auction style listing and a fixed price listing. Get it right and you can maximize your return. Get it wrong and you may be leaving real money on the table, or pricing yourself out of a sale entirely. Here is a breakdown of when each format works best and how to make the most of both.

When Fixed Price Makes Sense

Fixed price listings work best when you have solid, recent data to back up your asking price. eBay's completed and sold listings are your first stop for research, and eBay's built-in Product Research tool (available free in your Seller Hub, and known to many longtime sellers as Terapeak before eBay rebranded it) gives you access to up to three years of historical sales data on the platform. If a card similar to yours has sold consistently and repeatedly within that window, fixed price gives you confidence to set a firm number and hold it. Fixed price is also a practical choice for your more common cards, lower priced items, and anything where you have multiple copies to sell. The "Good Til Cancelled" format keeps those listings working for you around the clock without the need to reset them every 7 or 10 days.

When Auctions Are the Right Call

Here is where it gets interesting for serious collectors and sellers. If eBay's three year sold history shows little or no comparable data for a card you are holding, that is often a signal that the card is genuinely scarce. And scarce cards are exactly where auctions shine. When two or more motivated collectors discover the same rare item at the same time, competitive bidding can push the final price meaningfully higher than any fixed price you might have set in advance. The more unusual and desirable the card, the more an auction lets the market decide what it is truly worth rather than capping the outcome at a number you chose before the bidding began.

Going Deeper on Research: WorthPoint

When eBay's three year window does not show enough data, WorthPoint is the next tool to reach for. WorthPoint maintains a database of nearly 20 years of historical sold prices pulled from eBay and hundreds of auction houses, giving you a much longer view of the market for rare and infrequently sold items. If a card has only come up for sale a handful of times over the past decade, WorthPoint is often the only place you will find that transaction history. A paid subscription is required, but for serious postcard sellers it can pay for itself quickly by helping you make smarter pricing decisions on your best cards.

The Free Auction Listings You May Not Be Using

One thing many eBay store subscribers overlook is that their subscription comes with a set number of free auction style listings every month. These are yours to use at no additional insertion fee cost and reset each month, which means if you are not using them, you are leaving a benefit on the table. Here is a quick look at what each store level includes:

Store Level	Free Auction Listings Per Month
Starter	250
Basic	250
Premium	500
Anchor	1,000
Enterprise	2,500

Note that eBay restricts free auction listings to select categories, which include Antiques, Art, Collectibles, and several others — postcards fall comfortably within these categories so you are well covered. With a little planning, you can cycle through your most auction-worthy cards each month and put every one of those free listings to work. Think about which cards in your inventory are the most scarce or unusual, pull them out each month, and run them as auctions. Over the course of a year it adds up to a meaningful number of no-cost auction opportunities.

The Bottom Line

Think of fixed price as your workhorse format for the bread-and-butter cards in your inventory, and auctions as your high-stakes format for the cards where the sky is the limit. Match your research to the format, use your free monthly auction slots intentionally, and take advantage of both Product Research and WorthPoint to make sure you always know what you are working with before you list.
