1980 Dor-Tex Corp. Overview
The 1980 Dor-Tex Corp. Silver Trade Unit is a privately issued one-ounce silver round believed to have been produced during the early 1980s. The round was issued by Dor-Tex Corp., a Texas corporation incorporated in 1977 and originally headquartered in Dallas, Texas.
The piece is notable for its reverse, which shares a distinctive scales design with later Don Casey Company, Silvex Silver Systems, and Texas Mint trade units. The absence of the “Texas Mint” inscription found on later examples suggests the Dor-Tex issue may represent an earlier state of the design.
1980 Dor-Tex Corp. Notes
- Dor-Tex Corp. was a Texas corporation active from 1977 until its charter forfeiture in 2003.
- The company later operated under the assumed name Southwest Coffee Company.
- No evidence has been located that Dor-Tex operated its own minting facility.
- This is currently the only documented numismatic issue attributed to Dor-Tex Corp.
- Estimated production date of 1980–1981 is based on reverse die characteristics and the apparent absence of later Texas Mint branding.
