Coins sealed in plastic holders from PCGS or NGC, two of the major grading services, turn up often in Old Bridge estates and in collections people bought decades ago. The label on each holder shows a grade, a description, and a certification number. Heirs often read that label as a price tag, and it isn’t one.
When you sell graded coins in Old Bridge, a buyer checks three things before making an offer. First, the buyer looks up the certification number in the grading service’s database. Next, it checks the holder for damage or tampering. Last, it compares the coin and grade with what that coin sells for now. The label saves the buyer time, and the offer still depends on the current market.
A slab is the sealed plastic holder a grading service puts a coin in after grading it, with a label that identifies the coin and its grade. Collectors Coins & Jewelry in Old Bridge buys gold and silver coins and bullion, and the steps below are the same ones any careful buyer follows.
What Does the Label on a Graded Coin Mean?
The number on the label comes from the Sheldon scale, which runs from 1 to 70. NGC explains on its grading scale page that 60 is the threshold for a coin to count as uncirculated, and a 70 has no post-production imperfections at 5x magnification. The letters in front of the number describe how the coin was made. MS, for Mint State, means a coin struck for circulation, and PF means a proof coin struck for collectors.
NGC’s labels carry, at a minimum, the coin’s description and grade, a unique certification number, and a barcode. Some labels add a variety, a special designation, or a pedigree. NGC also warns that any quantity or number printed on its label is for numbering only. A label reading “1 of 500” doesn’t mean only 500 of that coin exist.
How Does a Buyer Verify the Certification Number?
Each grading service runs a free lookup. On a standard PCGS holder, the cert number is the 7- or 8-digit number after the slash, and the PCGS Cert Verification page returns the record for that coin. PCGS says the lookup also shows pricing and population data, meaning how many coins it has graded at each level, and that checking the number helps reduce the risk of buying a counterfeit or altered coin. NGC’s buying guide tells collectors to check its Verify NGC Certification tool for the grade, description, and any designation before a sale.
The buyer then compares the record with the coin in hand. The date, mint mark, denomination, and grade in the database should match the label, and the coin should match the description. PCGS notes that a data entry error can occasionally cause a mismatch, so a difference calls for a closer look rather than an automatic no.
The holder gets a physical check too. NGC states that counterfeit and altered holders are rare but do exist, and its holders use an ultrasonic seal and a hologram for that reason. A buyer looks for cracks, a seal that looks disturbed, or a label that looks reprinted, since a coin that has left its holder no longer carries that grade.
Why Isn’t the Grade the Same as the Offer?
A grade describes condition, and the market sets the value. Two coins with the same grade can sell for very different amounts depending on the date, the mint mark, how many survive in that grade, and current demand. A graded modern bullion coin often trades close to the value of its metal, while a scarce older date in a high grade can bring far more than melt.
That gap between metal value and collector value is the main reason a graded coin is worth showing a buyer in person. A buyer looks at the coin and the record together and prices it against recent sales. Our Old Bridge post on when gold is worth more than its melt value covers how that premium works for gold. Collectors Coins & Jewelry in Old Bridge evaluates coins in front of you, and walk-ins are welcome.
Bring every graded coin in its original holder, along with any paperwork, receipts, or old price lists that came with the collection. Don’t crack a holder open to look at the coin more closely, and keep the holders out of heat and direct sun.
