Buying and Selling Comics in Australia: Grading, Key Issues and Posting

MV Guides · Comics

Two copies of the same comic can be worth $20 or $2,000. The difference usually comes down to four things: which issue it is, which version of the cover it is, its condition, and whether it's been graded. Here's what to look for if you're clearing out a long box, or buying a key for your collection.

1. Key issues: why some comics are worth so much more

A "key" is an issue collectors want for a particular reason, and it's where most of the money in comics is. The big one is a first appearance, the first time a character shows up. For example, Amazing Fantasy #15 is Spider-Man's first appearance, and Incredible Hulk #181 is Wolverine's first full appearance (#180 has a cameo on the last page). Other keys include first issues of a long-running series, famous covers, deaths and origin stories.

Film and TV news moves prices fast. When a character is announced for a movie or series, their first appearance often jumps, then cools off once the hype passes. If you're selling, it's worth keeping an eye on that.

2. Which version of the cover

On MVCollect, pick the cover or edition from the list when you list a comic, so it's compared with the same version in the Market Value guide.

3. Condition

Comics are graded on a 10-point scale, from 0.5 (Poor) to 10 (Gem Mint). Collectors use the names too: Near Mint is around 9.4, Very Fine around 8.0, Fine around 6.0 and Very Good around 4.0. Small differences at the top end are big money. For a sought-after book, a 9.8 can sell for several times what a 9.6 does.

When you check a raw (ungraded) comic under good light, look for:

If you're not sure between two grades, describe it as the lower one. Buyers remember the sellers who undersold condition.

4. CGC and CBCS grading

Graded comics are sealed in a hard plastic case (a "slab") with a label showing the grade. The two big comic graders are CGC and CBCS. Grading makes the most sense for keys and for books likely to come back at 9.4 or higher. For an everyday comic, the grading fees and postage both ways often cost more than the grade adds.

CGC's label colours tell you important things at a glance:

CBCS uses its own labels, so check its key if you're buying a CBCS slab. Always check the certification number on the grader's own website before you pay, and compare the label details with the book in the slab. Fake slabs exist for big keys. On MVCollect, graded comics show the cert number with a link to CGC's or CBCS's lookup, and the same cert number can't be listed twice.

5. Signed comics

A signature can add a lot or nothing at all, depending on whether it can be proven. CGC Signature Series (yellow label) and CBCS Verified Signature are the most trusted, because the signing was witnessed. A raw signed comic needs a certificate from PSA, JSA or Beckett (BAS) to be listed on MVCollect. Anything signed "in person" with no proof is treated as unsigned by most buyers.

6. Storing comics in Australia

7. Price it in Aussie dollars

Most comic sales happen in the US, so most price guides and sold listings are in US dollars. Look at what the same issue, same cover and similar grade actually sold for (not asking prices), then convert to Aussie dollars at the rate on the day it sold. MVCollect's Market Value guide shows real sold prices under Comics as sales come in.

8. Posting a comic without bending it

A bent comic is a ruined comic, so never send one in a soft envelope.

On MVCollect, comics post as a parcel: you enter the packed weight and size, and the postage is worked out for you.
