guess I needed the most recent one to keep the collection current, but I'm sure I've got more than a couple of 'holes' in my most recent slots (to fill). At 25 US$ per stamp, it's a little less than buying the older ones that easily go sometimes for >$100.
Hi Larry: Well, there is always the hope the new ones may appreciate and the older ones even more so. Don
When I collected in the 1960s the Ducks were Dogs on the market...I had quite a few of them and I doubt the entire lot was worth $50.
