The Online Selling Myth

On paper, selling comics online sounds perfect. List a few books. Sit back. Watch the money roll in.

In reality? For most collectors - especially those with collections, not just single key issues - online selling becomes frustrating, time‑consuming, and often financially disappointing.

If you’ve ever searched “Why online selling doesn’t work for comic collections?”, you’re not alone. Every week we speak to collectors who tried the online route first… and wish they hadn’t.

Let’s break down the most common mistakes people make when selling comics online, and why those mistakes usually cost more than they gain.

 

1. Over‑Reliance on Online Listings

The Illusion of the Perfect Platform

eBay, Facebook Marketplace, Whatnot, Etsy - they all promise massive audiences and quick sales. What they don’t advertise is the competition that you gain by using these platforms.

Thousands of identical comics are listed every day. Unless you’re selling a truly rare, high‑grade key, your listings are just one drop in a very large ocean.

The Harsh Truth

Most common comics:

  • Sit unsold for months

  • Sell only after price drops

  • Attract low‑ball offers

  • riddled with scammers

Online platforms work best for individual highlights, not entire collections. If you've got the time to put in, this very well may be the best option in terms of profit, but expect it take a VERY long time.

 

2. Expecting Collection Value to Equal Individual Prices

One of the biggest misconceptions in comic selling is this:

“If each comic is worth £10, my 200‑comic collection must be worth £2,000.”

Unfortunately, that’s not how the market works.

The Reality of Bulk Selling

When selling on online marketplaces, buyers want:

  • Complete runs

  • Clean breaks

  • Minimal filler

Loose issues, duplicates, and broken runs dramatically reduce appeal. Online buyers aren’t building collections - they’re filling gaps.

Broken runs are one of the biggest value killers when selling online.

 

3. Poor Descriptions (And Why They Matter)

“Looks Good for Its Age” Isn’t Enough

Online buyers rely entirely on your description and photos. Vague listings signal risk — and risk lowers prices.

Common description mistakes include:

  • No mention of defects

  • Over‑grading condition

  • Missing issue numbers

  • No indication of restoration or damage

The result?

  • Returns

  • Disputes

  • Negative feedback

  • Forced refunds

All of which cost time and money.

 

4. Broken Runs: The Silent Collection Killer

Collectors love continuity. Online buyers love completion.

A run missing key issues is far harder to sell than a complete - or even near‑complete - one.

Example:

  • Issues #1–50 missing #1, #15, and #25

To an online buyer, that’s a headache - not a bargain, even if it's a half off.

When selling comics individually online, breaking runs to sell key issues first often leaves the remaining issues almost unsellable.

 

5. Underestimating Fees, Postage, and Time

Online selling isn’t free.

Between:

  • Platform fees

  • Payment processing

  • Postage

  • Packaging materials

  • Lost parcels

  • Returns

Your final profit is often far lower than expected.

Time Is the Hidden Cost

Photographing, listing, answering questions, packing, posting — repeat that hundreds of times and the hourly rate quickly becomes depressing.

For full collections, online selling rarely scales well.

 

6. Chasing “Sold Listings” Without Context

Checking sold prices online is useful - but dangerous without experience.

Common Pitfalls

  • Confusing slabbed prices with raw books

  • Ignoring condition differences

  • Missing special variants

  • Overlooking seller reputation

This leads to unrealistic expectations - and listings that never sell.

A comic is only worth what someone will pay right now, not what one perfect example sold for six months ago.

 

7. Emotional Pricing and Hesitation

Sentiment doesn’t translate online.

Buyers don’t care:

  • What you paid

  • Where you bought it

  • How long you owned it

Overpricing due to emotional attachment leads to stagnant listings and eventual price drops.

Worse still, hesitation causes sellers to drip‑feed listings over months or years - often abandoning the process entirely.

 

8. Why Online Selling Rarely Works for Comic Collections

Online platforms are designed for transactions, not collections.

They work best when:

  • The item is clearly defined

  • Condition is obvious

  • Demand is immediate

Collections are the opposite - varied condition, mixed desirability, and uneven demand.

That’s why so many sellers eventually look for an alternative.
