Where do South Plainfield residents sell gold for cash?
At Cash 4 Gold Trading Post, 748 Bound Brook Rd in Middlesex. The store sits on Route 28 between Dunellen and Bound Brook, and from Hamilton Boulevard most drivers work north toward Dunellen, pick up Route 28, and follow it west into Middlesex Borough. Depending on lights it takes 10 to 15 minutes. It is the closest counter to the borough whose whole trade is buying gold, silver, platinum, diamonds, and coins.
South Plainfield is a borough of about 24,000 people, and the trip looks much the same from Oak Tree Road, the streets off Maple Avenue, or the homes near Spring Lake Park: north, then west on Route 28.
What South Plainfield families bring in
South Plainfield became its own borough in 1926, when it separated from Piscataway Township, and it grew as a working town: factories and warehouses along Durham Avenue and the rail lines, and houses that the same families have kept for two and three generations. Hadley Road still carries the name of Hadley Field, the airfield here that handled air mail in the 1920s.
That history shows up at the counter as gold that was worn, not collected. We see wedding bands, South Plainfield High School class rings, union and service pins, a father's watch, and coin rolls saved in a coffee can. None of it needs to be cleaned or matched up first. Gold is bought on purity and weight, so a broken chain or a single earring counts exactly the same as a whole one.
When a South Plainfield house is being cleared
Long-held houses tend to empty out all at once: a jewelry box, a sterling service in its chest, a pocket watch, and a folder of old silver coins. Each of those is worth a different amount per gram, so each is counted on its own. Diamonds are graded first, gold is split by karat, sterling is weighed apart from plate, and coins are checked by date and condition before their metal is counted.
If the house is full or the owner cannot travel, ask about the estate buyers service, which covers house calls and paperwork for executors. The New Jersey estate jewelry guide lists what to set aside before anyone sees it.
What a customer at the Middlesex counter wrote

The stone and the setting are two separate offers
A diamond ring is graded as a stone and priced as a band, separately. The diamond is looked at under magnification for carat, cut, color, and clarity, with a GIA or IGI report or without one, and the gold or platinum setting is priced on that day's spot. That split is what keeps a good stone from being paid as scrap. See the diamond buyers page or read where to sell an engagement ring.

Where is the closest gold buyer to South Plainfield?
Cash 4 Gold Trading Post at 748 Bound Brook Rd in Middlesex, on Route 28 between Dunellen and Bound Brook, about 10 to 15 minutes from Hamilton Boulevard. We buy gold, silver, platinum, diamonds, and coins outright and do not lend. Call (732) 629-7600 with any question.
Do you buy South Plainfield High School class rings?
Yes, and class rings from any school. They are bought for their gold, which is usually 10k or 14k, and the XRF reading shows you which before you hear a number.
Are old silver coins worth more than their silver?
Sometimes. Coins are checked by date and condition before their metal is counted, because a better date can be worth more to a collector than to a smelter. Bring the whole roll or folder and let each one be looked at.
Should I clean jewelry before I bring it in?
No. Tarnish and broken clasps do not lower a gold offer, and polishing can scratch a stone or wear down a hallmark. Bring everything as it is.
What decides the offer on gold from South Plainfield?
The XRF purity reading, the weight on a certified scale, and the live spot price that day. The offer moves with the market, not with the town you drove from.
Is selling different from a pawn loan?
Yes. A pawn loan borrows against a piece, which stays with the lender until you repay with interest. A sale is final and you owe nothing. We only buy, so if you want the item back later, see a licensed pawnbroker.
What ID do I need to sell gold in New Jersey?
A valid government photo ID, such as a driver's license or passport, for every precious-metals sale. No receipts or appraisals are required.
