SJT
San Juan Basin Royalty Trust UBI
stock NYSE

The short answer is that unless you’ve found a very rare collector’s item, the stock itself is likely not redeemable for cash today. Most companies with this exact name were active during the mining booms of the late 19th and early 20th centuries and have long since dissolved.
Here is a breakdown of how to determine if your specific certificate has any value:
### 1. Financial Value (Redeemable Shares)
For a stock certificate to have actual trading value, the company must still be active or have been acquired by a successor that is still in business.
* **The Verdict:** The "San Juan Mining and Developing Company" (often incorporated in Colorado or Utah around the 1870s–1900s) is generally considered **defunct**.
* **Common Confusion:** Do not confuse this with the **San Juan Basin Royalty Trust (Ticker: SJT)**. SJT is a modern, active energy trust traded on the NYSE (currently around **$4.30–$4.50 per share**), but it was founded in 1980 and is a completely different entity from the historical mining companies.
### 2. Collectible Value (Scripophily)
Even if the company is dead, the physical paper can be worth money to collectors of historical documents (a field called *scripophily*).
* **Aesthetic Value:** If the certificate features ornate engravings, "vignettes" (pictures) of miners, or gold-leaf seals, it is more desirable.
* **Price Range:** Typical mining certificates from that era sell for **$20 to $100** on sites like eBay or through specialized dealers like Scripophily.com.
* **Historical Significance:** If it is signed by a famous historical figure or comes from a specific famous district (like the Eureka District in Colorado), the price can go higher.
### 3. How to Verify for Sure
If you want to be 100% certain there isn't a "zombie" company out there that owes you money:
* **Check the State of Incorporation:** Look at the fine print on the certificate to see where the company was registered (usually Colorado or West Virginia). You can search that state’s **Secretary of State** website for "Business Entity Search" to see if they have a record of a merger or dissolution.
* **Unclaimed Property:** Search the [National Association of Unclaimed Property Administrators](https://unclaimed.org/) (specifically for the state where the original owner lived). If the company was bought out, the cash for those shares might be sitting in a state fund waiting for a claim.
**Quick Tip:** If you're looking at the certificate right now, check the **incorporation date**. If it’s before 1950, it is almost certainly a "decorative" piece rather than a functional investment.
