Well this box of halves wasn't out of this world but at least I wasn't skunked. Three 40%-ers (1967, 1968-D, 1969-D) and a 2003-D. Found my first gold-colored half, 1972, but it had no additional dates stamped onto the front.
Congratulations on the sliver Immy! None of the gold electroplated halves that I have found have any additional dates stamped on them,but I keep hoping I'll find one like that. Any box that yeilds silver is a good box in my book. I've had plenty that had no silver. lol I'm picking up my three boxes tomorrow so I'll post the results,and hope I find some silver.
