Top 20 Dungeons and Dragons Modules in 2025

Most Valuable Dungeons and Dragons Modules in 2025

What is a D&D module?

It's not clear why they chose this name, but essentially modules were complete adventures.

The creators of D&D sold them as ready-to-go adventures or mini-campaigns for players to use.

While the Dungeons and Dragons game offers total freedom to customize and imagine whatever you like, some people just aren't creative enough to do this.

Modules took the pain and trouble out of dungeon mastering.

They were typically two- or three-part items:

• an outer folder, which was usually one color plus black and white;
• the inner pages, which were stapled together but not attached to the outer folder;
• and sometimes a map, or other insert

Maps were often printed on the inside of the outer folder.

There are multiple printings of the earlier modules. Some printings are rarer than others.

The card stock used for the outer folder in the early years was prone to bends, cracking and splitting. Later years, they used better-quality card, and later modules came stapled together like comic books.

Later modules are often found in much higher grade than early ones as a consequence.

Top 20 Dungeons and Dragons Modules in 2025

Dungeons and Dragons Modules: B3 Palace of the Silver Princess, orange

Lowest price $750

Average price $3,000

Record price $10,000?

The original orange-cover version of B3 was never sold to the public. TSR reworked it due to editorial concerns.

One box of 72 copies escaped the shredder. See this page explaining the history at Acaeum.

One high-grade copy is currently listed on eBay with an asking price of $12,000.

D&D Module C1 Lost Tamoachan Limited Edition (1979)

Lowest price $??

Average price $2,000

Record price $8,000

The original limited edition of this module is among the most sought-after of Dungeons and Dragons modules. Later editions were named C1, Hidden Shrine of Tamoachan. The first printing of the new version is also rare.

A VG+ copy was listed on eBay early in 2025 with an asking price of $10,000. It was withdrawn, so our price is an estimate. Later printings are less valuable.

D&D Module ST1 Up the Garden Path (1986)

Lowest price $1,500

Average price $5,000

Record price $9,000+

Printed in low numbers for a UK event in 1986, this is one of the must-have Dungeons and Dragons modules for advanced collectors.

I personally bought and sold one in 2002 -- the selling price was around $1,000 at the time. A copy sold in 2024 at an online auction website for $9,000.

D&D Module D3 Vault of the Drow 3rd Printing

Lowest price $50

Average price $150

Record price $4,500

The market for graded Dungeons and Dragons modules is still in its infancy. This sale of a CGC 8.5 reflects the new market conditions. Expect later sales for actually lower prices in the future, as more copies are graded.

The first printing is much harder to find.

D&D Module R1 To the Aid of Falx (1982)

Lowest price $500

Average price $900

Record price $3,500

A single printing is known of the original R1 module. The record sale of an 8.5 graded copy is $3,360.

D&D Module S1 Tomb of Horrors (1978)

Lowest price $50

Average price $300

Record price $1,330

The record sale for a first printing so far is $1,330 for a graded 8.5 copy. It will surely be beaten if a higher grade comes to market.

D&D Module R3 Egg of the Phoenix (1982)

Lowest price $40

Average price $100

Record price $780

The record sale for a CGC 7.0 of the original orange and brown version. There is a much rarer pre-production version which is much more valuable.

D&D Module CM8 The Endless Stair (1987)

Lowest price $5

Average price $40

Record price $660

This is a relatively recent module and not rare. A 9.4 sealed copy is the record holder.
