All are used. And i believe all have numbers glued on the bottom and they have had weights glued on their insides. See pics for example. I didn't open all of them. And it looks like the coal cars have homemade coal loads. They do have micro trains couplers and trucks. The owner ran these on a huge layout. Theres multiples of most of them. I think theres like 7 of the same cars. Boxes have wear and looks like they match up with the train car. Saw a few that had a broken ladder on the side. But overall they'd be nice for any layout. Shipping is 12.00. I will ship out within three three days after payment received
