Tin vs Zinc
Tin and Zinc are easy to confuse because both are metals & alloys. Zinc is harder (Mohs 2.5) than Tin (Mohs 1.5), so Zinc will scratch Tin and not the other way round. A fingernail (Mohs 2.5) scratches it easily. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Tin and Zinc
- Zinc is harder (Mohs 2.5) than Tin (Mohs 1.5), so Zinc will scratch Tin and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
- Streak color differs: Tin leaves a silver-gray streak on unglazed porcelain, Zinc leaves gray.
- Both look metallic, so compare color, tarnish and weight rather than shine.

Which is more valuable?
Tin is usually the more valuable of the two: a typical collector specimen runs about $15 against $10 for Zinc, and premium Tin can reach $120 or more.
About Tin
Tin is a soft silvery metal used in solder, coatings, alloys, pewter, and some decorative or educational metal samples.
About Zinc
Zinc is a bluish-silver metal used in galvanizing steel, die-cast objects, batteries, coins, hardware, and brass production.
Tin vs Zinc FAQ
Is Tin the same as Zinc?
No. Both are metals & alloys, but they are distinct species with different hardness, streak or luster. Zinc is harder (Mohs 2.5) than Tin (Mohs 1.5), so Zinc will scratch Tin and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
How can you tell Tin from Zinc?
