I've had these for a long time. I bought them from T Levin's website when he was still offering them. Since they haven't been offered since 1999, they are at least 7 years old.

They are in very good condition, but they do have signs of wear/age. I'll be posting pictures at some point.
I'm looking for $45 shipped US. Yes, you could make them yourself for less. Knock yourself out (you can even see how in the link above). If you want originals with the picture of the bear on them, it's $45.
A set autographed by Tony went for well over $100 just a couple of weeks ago.
