You’re standing in your garage or at a local muffler shop, looking at that rusted, honeycomb-filled cylinder that just came off your car. It looks like junk. It feels like junk. But you've heard the stories about people crawling under trucks in the middle of the night just to saw these things off. You’re wondering how much catalytic converter scrap value you’re actually sitting on. Is it $50? Is it $1,500?
The truth is, the market for these things is more volatile than a tech stock during an earnings call.
If you walk into a scrap yard expecting a flat rate, you’re going to get burned. Dealers don't buy "catalytic converters" as a generic item; they buy the microscopic grams of platinum, palladium, and rhodium trapped inside that ceramic brick. Some cars have three grams. Some have fifteen. That difference is the gap between a nice steak dinner and a down payment on a used Harley. Honestly, the industry is a bit of a "wild west" for the uninitiated.
Why the Value Swings So Wildly
Let’s talk about the chemistry for a second. Inside that shell is a ceramic monolith coated in PGMs (Platinum Group Metals). These metals are incredibly rare. According to the United States Geological Survey (USGS), South Africa and Russia control the vast majority of the world's supply. When geopolitical tensions rise or mining strikes happen in the Bushveld Igneous Complex, your old Toyota Prius converter suddenly becomes a hot commodity.
Rhodium is the real king here. While platinum gets all the jewelry fame, rhodium is the heavy lifter for scrubbing nitrogen oxides from exhaust. In the last few years, rhodium has seen price spikes that make Bitcoin look stable, sometimes hitting over $20,000 per ounce before crashing back down to $4,000.
Because of this, a "price list" you found on a forum six months ago is basically useless today.
Identifying What You Have
You can't just say, "I have a Ford converter." That’s like saying you have a "blue book." It tells the buyer nothing.

To find out how much catalytic converter units are worth, you need the serial code. This is usually a stamped string of numbers and letters on the outer casing. On a GM part, it might be a long string; on a Volkswagen or Audi, it’s often a combination like "7L6 131 701." If the shell is too rusted to read, you’re in trouble. Scrappers call these "rusties," and they usually pay a flat, low-ball "aftermarket" rate for them because they can’t verify the PGM load.
Foreign converters, especially from German and Japanese manufacturers, generally hold more value than domestic ones. A 2005-2010 Toyota Prius (the Gen 2) is the "holy grail" for a reason. It uses an exceptionally high amount of palladium and rhodium because the hybrid engine frequently turns on and off, requiring the converter to stay "active" and efficient even when it isn't at full operating temperature. These can easily fetch $500 to $1,000 even in a down market.
Compare that to a "pre-cat" from a small domestic sedan, which might only be worth $40.
The Aftermarket Trap
Here is a mistake almost everyone makes: they replace their OEM (Original Equipment Manufacturer) converter with a cheap one from an auto parts store, then try to sell the old one. That’s fine. But then, three years later, that cheap replacement fails, and they try to scrap it.
Stop.
Aftermarket converters—the ones you buy for $150 to pass an emissions test—are worth almost nothing in scrap. Maybe $5 or $10. Why? Because they are designed to be cheap. They use the bare minimum of precious metals to meet legal standards for a short period. Scrap yards can tell the difference instantly by the shape, the lack of an OEM stamp, or the shiny, thin heat shields. If you bought it at a chain parts store, don't expect a payday.

How the Pros Actually Grade These
If you watch a professional buyer work, they aren't guessing. Large-scale recycling companies like PGM of Texas or PMR use XRF (X-ray fluorescence) analyzers. These look like futuristic ray guns. They point the gun at the ceramic dust, pull the trigger, and the screen tells them exactly how many parts per million of platinum are inside.
For the average person, you'll be dealing with "grading." Buyers categorize them into buckets:
- Large Bread Loaf: Usually from trucks or vans.
- Torpedos: Long, sleek ones often found on older luxury cars.
- Exotics: High-end sports cars or specific hybrids.
- Pre-cats: Small units located right near the manifold.
The "fullness" of the unit matters too. If you shake the converter and it sounds like a box of broken glass, it’s "de-canned." If half the honeycomb has blown out the tailpipe over the years, you’re only getting half the money.
The Legal Headache You Can't Ignore
Because of the massive spike in thefts, laws have changed everywhere. You can't just walk into a yard with a trunk full of converters and walk out with a stack of hundreds. In many states, like California or Texas, scrap metal dealers are required to take a copy of your ID, photos of the part, and sometimes even a copy of the vehicle's registration.
Many yards won't even buy from individuals anymore. They only deal with licensed businesses or automotive shops. If you’re a DIYer who just replaced yours, you might have to search for a "full-service" recycler that accepts "public" walk-ins. Expect to wait for a check in the mail; "cash on the spot" is becoming illegal in many jurisdictions to deter thieves.
Maximizing Your Payout
If you want to know how much catalytic converter value you can squeeze out, don't just go to the nearest "We Buy Junk Cars" lot. Those guys are middlemen. They’ll buy it from you for $100 and sell it to a processor for $200.

Search for "core buyers" or "specialized PGM recyclers." There are even apps now—like Eco-Cat or various online databases—where you can plug in your serial number. They will give you a quote based on that day's market price. You ship it to them, they refine it, and you get a much fairer shake.
Also, never, ever "gut" the converter. Some people think they are helping by breaking the ceramic out of the metal shell. You’re actually making it harder to value. Once the ceramic is a pile of dust, the buyer has no way of knowing if it came from a high-value Prius or a low-value Ford Focus. Keep it in the shell.
Current Market Realities in 2026
We are seeing a weird shift in the market right now. As electric vehicles (EVs) become more common, the long-term demand for these metals is technically threatened. However, because new internal combustion engines have to meet increasingly "Euro 7" or similar strict emissions standards, the amount of PGM required per car is actually increasing.
The supply of scrap is also tightening. Cars are staying on the road longer. This keeps the floor for scrap prices relatively high compared to the early 2010s. If you have a diesel converter (DPF - Diesel Particulate Filter), you're in an even better spot. Those are huge, heavy, and often contain significant amounts of platinum.
Actionable Steps for the Seller
- Find the Code: Get under there with a rag and some WD-40. Wipe the shell until you see stamped numbers. Take a clear photo.
- Verify the OEM Status: Look for a manufacturer logo (Toyota, GM, Ford). If it says "Made in China" or has no logo, lower your expectations to "pocket change" levels.
- Check the Honeycomb: Shine a light through it. If you can see the intact "screen" on both sides, it's a "Full" unit.
- Avoid Middlemen: Skip the scrap yard that buys old washing machines. Look for a buyer that only does catalytic converters.
- Watch the Metal Markets: If you can afford to wait, keep an eye on palladium prices. If palladium is tanking, hold onto your part for a month or two.
- Bring Paperwork: Have your VIN and ID ready. Being prepared makes you look like a legitimate seller and not someone who just "found" it in a parking lot.
Ultimately, the value of your scrap is a math problem involving the weight of the ceramic, the PGM loading of that specific model, and the London Fix price of precious metals at the exact hour you walk through the door. It’s a complex, dirty, and sometimes frustrating business, but if you have the right serial number, it’s one of the few pieces of "trash" that can actually pay your rent.
Next Steps:
Identify the serial number on your unit and use a reputable PGM price database to get a baseline quote before visiting a local buyer. This ensures you have leverage during the negotiation.
