Numismatic Value — What Collectors Pay Today
The market value depends heavily on condition (grade), variety (metal/error), presence in original packaging, and demand. Typical observations:
- Circulated coins (G–VF): usually close to face value, often $1–5 USD.
- Uncirculated / BU coins: can reach $5–15 USD, depending on demand and seller. Coins in original mint sets may be more valuable.
- Rare varieties / proof / silver / errors: Proofs or coins with minting errors may be worth significantly more — sometimes tens of dollars or higher if certified.
Example: Circulated 1987 coins are often listed for $2–10 USD, while higher-grade coins can fetch higher prices depending on condition.
How to Properly Evaluate a Coin
- Check composition and variety: Ensure it is the aluminium-bronze version (most common for 1987).
- Assess condition (grade): Scratches, wear, original luster, and edge markings significantly affect value. Certified coins (NGC/PCGS/NV) are easier to trade.
- Look for errors or minting variations: Misstrikes, double strikes, or edge differences can increase value.
- Check for original packaging (unc sets) or proof coins: Mint sets with coins in pristine condition command higher premiums.
Where to Buy / Sell
- Online market: eBay, specialized coin shops, and marketplaces — good for price comparison.
- Local coin dealers / fairs: Useful for physical inspection and valuation.
- Auction houses and certification services: Rare or high-grade coins can reach higher prices with professional certification.
Conclusion
The Singapore 1 Dollar coin (1987) is a representative piece of the Floral Series, featuring an attractive periwinkle design and standard specifications (aluminium-bronze, ~6.3 g, 22.4 mm). For most collectors, it is low to moderate in value as a circulation coin; potential appreciation comes with uncirculated coins, proofs, or rare varieties/errors. Always confirm variant, condition, and certification before buying or selling, and compare current listings for a fair price.
