I don't know the embossing index here, just that it's a CREB, W. Brookfield/45 Cliff St./N.Y. with no mold # or patent. It's pictured next to my bluest CD 133 [230] to show off the green color. Condition is great, just a couple pings, one in wire groove another on base but not too noticeable for $50 postpaid.
