Hot Wheels Case Letters Explained: What A Case, G Case and Q Case Mean

If you've spent any time in Hot Wheels groups, you'll have seen people talking about the "G case", "J case" or "Q case". It sounds like code, but it's simple once you know what to look for, and it's one of the most useful things a collector can learn, especially if you're hunting Treasure Hunts.

What is a Hot Wheels case?

Shops don't order mainline Hot Wheels one at a time. Mattel ships them in sealed cardboard cases, each holding a mix of different cars. In the US a mainline case holds 72 cars. Each year's mainline range is split into 15 case mixes, and every mix has a letter:

A, B, C, D, E, F, G, H, J, K, L, M, N, P and Q

The letters I and O are skipped, so they can't be mixed up with the numbers 1 and 0. The cases come out in order through the year, so A cases arrive first, around the start of the year, and Q cases arrive last.

Why the case letter matters

• New castings and First Editions debut in a particular case, so collectors know when to start looking for them.
• Treasure Hunts and Super Treasure Hunts are usually only found in one case mix. If you know which case a TH is in, you know which wave of stock to hunt through.
• Carry-over cars appear in more than one case. A car that debuts in one mix can turn up again in the next, so its release date isn't always the same as its case letter.

How to read the case code on the card

Every carded mainline has an assortment code printed on the back, near the barcode. It looks something like L2593-976K PN. Here's how to read it:

• The first part tells you the market. L2593 is the US long card assortment, C4982 is the international assortment, and 5785 is the short card assortment.
• The last letter in the middle block is the case mix. In L2593-976K, the case is K.
• The two letters at the end are the version. Later letters in the alphabet mean a later production run.
• A separate date code shows when the case was packed.

Store cardboard cases have the same codes printed on the side of the box, which is how collectors spot a fresh case on a shop floor.

Case letters and UK collectors

Most mainlines in UK shops are short cards, and UK stock often arrives later than in the US, so a "new" case in America can take a while to reach British shelves. That's one reason UK collectors buy online: the car you missed in the shops may already be here.
