1972 is the year I use, Jerry. The regulation be came effective but matches in stock and in process could still be used. Also, any matches in the customer's stock could be used, so there is no distinct dividing line.

I'd say your full book front strikers are worth in the $2-7 range each from a dealer. For those who collect varieties (as I do) it helps to show the inside of the book. There are at least 8 green/white Trop matches of the style you show. I am missing some in full-book form and might be interested in yours.

The Royal Casino isn't seen too often.
