A small discovery in a coffee shop tip jar can turn into a lesson in numismatics. A Roosevelt dime found among modern change may be older and made of silver. This guide explains how a Roosevelt dime found in a coffee shop tip jar turns out to be silver, how to check it, and what steps to take if you find one.
Why a Roosevelt dime found in a coffee shop tip jar might be silver
Roosevelt dimes were produced in silver at a specific time in U.S. history. Coins dated 1964 or earlier were struck in 90% silver. Many older dimes survive in circulation and can still appear in everyday places like tip jars.
Because people often drop spare change into tip jars without checking dates, it is not unusual for an older silver dime to turn up in a modern business. Knowing the basics helps you spot one quickly.
Key identification points for a silver Roosevelt dime
- Check the date: Dimes dated 1964 or earlier are 90% silver.
- Examine color and tone: Silver coins have a different sheen and may show darker toning.
- Listen for the ring: Silver coins produce a higher-pitched, clear ring when tapped gently.
- Weigh and measure: Silver dimes have a known weight and diameter you can check with a scale and calipers.
How to tell if a Roosevelt dime is silver
Use safe, non-destructive tests before trying anything that could damage the coin. Start with the date and visual checks, and then move to simple tests you can do at home.
Step-by-step checks
- Read the date on the obverse. If it is 1964 or earlier, the coin is likely 90% silver.
- Look at the edge: older silver dimes have reeded edges like modern dimes, but the appearance and wear differ.
- Do the sound test: place the dime on a hard surface or tap it gently with another coin; silver often rings more cleanly than clad coins.
- Try the magnet test: silver is not magnetic. If a magnet strongly attracts the coin, it is not silver. This test only detects ferromagnetic materials and is not definitive on its own.
- Weigh the coin: a silver Roosevelt dime should be close to its standard mass. Use a digital scale accurate to 0.01 grams.
Authenticating without damaging the coin
If the initial checks suggest the dime is silver, use a few careful techniques to confirm authenticity. Avoid destructive tests like acid unless you plan to sacrifice the coin.
Non-destructive authentication methods
- Digital scale: Compare the weight to the standard for silver dimes (expect slight variation from wear).
- Specific gravity test: Measure mass and apparent mass submerged in water to estimate metal density. This is more precise and non-destructive.
- Professional appraisal: Take the coin to a reputable coin dealer or local coin club for expert verification.
What to do if you find a silver Roosevelt dime
Decide whether to keep it for its silver value, sell it, or have it graded. Your choice depends on the coin’s date, mint mark, and condition.
Options after identification
- Keep: Hold it as part of a small collection or as an interesting keepsake from the tip jar discovery.
- Sell for melt value: If the coin is common and worn, it may be worth its silver content.
- Sell to collectors: Rare dates and mint marks can be worth more than melt value if the condition is good.
- Get graded: For potentially valuable coins, professional grading can secure a higher sale price.
Case study: A coffee shop find and the steps taken
At a small cafe, a barista noticed an older-looking dime in the tip jar while counting cash. The coin’s date read 1954. Curious, the barista followed basic checks before deciding what to do.
First, they checked the date and visually inspected the coin for toning and wear. Next, they performed a simple ring test and used a small digital scale to confirm the weight was consistent with a silver dime. Finally, they took the coin to a local coin dealer who confirmed it was a 90% silver 1954 Roosevelt dime and advised keeping it due to modest collector interest.
This case shows how a quick, careful approach can identify and preserve an old coin found in a common place.
Practical tips and caution
When handling old coins, use clean hands or cotton gloves to avoid oils and scratches. Store valuable or potentially valuable coins in protective holders to prevent damage.
Quick checklist
- Check the date first: 1964 or earlier likely means silver.
- Do non-destructive tests: visual, sound, weight, and magnet tests.
- Get a professional opinion for potentially valuable pieces.
- Store coins safely if you decide to keep them.
A silver Roosevelt dime found in a coffee shop tip jar is a neat reminder that small treasures can still appear in everyday life. With a few simple steps you can identify, authenticate, and decide the best course of action for the coin.
