Some of those old B.C. coins are worth money, some just a few dollars- condition, date, rarity, demand- all enter into it. The tetradrachma is a nice keepsake, anyway.

I wanted the 50 state coins, from both mints (100), but being in Canada, I couldn't get them from a bank.
I ordered the whole smear, 'brilliant uncirculated' for $70 plus shipping, and two holders. Cost me $100 in all, or $1.00 per quarter. A little expensive, but they are fresh and bright and nice to have.
I see they have put them out for the territories as well.

I am just a sometime collector, and have all those my parents collected. They had a temporary job in Dallas, and were staying in a hotel; I was with the grands. To pass time in the evenings without going out (those were radio days) they would get sacks of pennies dimes, quarters, etc. from the bank near them and sort them, keeping the best. They got Lincoln pennies and barber pole dimes complete (two sets each) and a fair swatch of halves.

I tried the same when I came to Canada, but after 3-4 years the banks started checking the silver coins on their own. At my bank, a pensioner sat at a desk with a hand lens, sorting change, and took all of the joy out of that method of cheap collecting.

I probably will buy the Parks as well.
