How do you get from Somerset Street to Bound Brook Road?
Head south over the Green Brook into Plainfield and pick up Route 28 going west. It runs through Dunellen and into Middlesex borough, where it takes the name Bound Brook Road, and the store is at number 748 on the way. From the Route 22 side of the borough, add a few minutes to get down to the brook first. Allow around twenty minutes, longer at the evening rush.
Because the Middlesex store is open on Saturday and closed on Sunday, plenty of North Plainfield sellers fit it into a weekend errand run. A question about a single item can be answered by phone first at (732) 629-7600.
Not Plainfield, even if the mail says so
North Plainfield broke away as its own borough in 1885, after starting out as part of a larger township that also took in what is now Watchung and Green Brook. It covers under three square miles at the foot of the first Watchung ridge, it belongs to Somerset County while Plainfield belongs to Union, and it still shares Plainfield's ZIP codes, which is why so many residents are asked which Plainfield they mean. The Washington Park Historic District preserves the late 1800s houses from the years the borough grew as a commuter suburb.
Most of what we see from here is ordinary family gold, the kind that piles up over forty years in one house: wedding bands from two generations, a single earring whose partner went missing, broken necklaces, class rings from North Plainfield High, a charm bracelet, and a pocketful of pre-1965 dimes and quarters someone set aside. None of it needs to be cleaned, matched or repaired to be sold.
How a bag of odds and ends is valued
A mixed bag is the easiest thing to underpay, so it is taken apart before anything goes on the scale. The XRF reads each item: 14K is 58.5 percent gold and 10K is 41.7, and pieces that turn out to be plated are set aside and shown to you rather than quietly bought. Each karat group is weighed on its own and priced against the live market that day.
Pre-1965 US dimes, quarters and half dollars are 90 percent silver and are counted as such, with any key date or better-grade coin pulled out for its collector value first. A broken chain is worth exactly what an intact one of the same weight and karat is worth, so there is no reason to have it fixed. See the coin buyers page or how gold jewelry is valued.

Do you buy broken chains and single earrings?
Yes. Gold is priced on karat and weight, so a broken or unmatched piece is worth the same as an intact one of equal weight and purity.

Yes. US dimes, quarters and half dollars from before 1965 are 90 percent silver, and each is checked for collector value before silver content is counted.
Is the Middlesex store open on weekends?

What ID do I need?
A valid government photo ID. New Jersey requires it to be recorded for every precious-metals sale.
