There are several places on Route 38 between Mt. Holly and Creek Road. There's one I like a lot there, it's on the West Bound side of Rt 38, near Creek Road in Hainesport. It's called Country Antiques. It's pretty large and has a nice section with old books, magazines, post cards etc. Their phone is 609-261-1924.
This is not in the pines but it's quite a place if you ever get to Pennsylvania. Merritt's Antiques in Douglasville PA. Take Rt 422 to Rt 662 North. Bear left at the fork on Weavertown Rd, they are on the left. They have a
website . Since I am involved with stage scenery I've used this place a lot; it's HUGE and the people there are great. Really worth the trip if you're into this sort of thing. Even Broadway designers and movies shop there.
And of course I should mention my home town, Medford NJ where there are
a number of places. My favorite is Toll House Antiques on Old Marlton Pike and Hartford Rd. If you go, be sure to check out the back room which is strange stuff, as-is at generally low prices.
