This would have to be my earliest purchase. Well, actually, my grandmother bought it for me.
We had a department store here in Buffalo called 'Sattlers'. I think there were a few of them, but the one downtown had a coin department. They had a "Berg-motion case" with the shelves full of coins. I remember standing there with my finger on the button, watching the shelves rotate and looking for something affordable. I think it was the 'moon and star' on this 1947 Turkish 50 Kurus that really intrigued me.
My maternal grandmother liked to shop downtown, and if I would go with her and behave, the reward would be a coin from Sattlers. I picked out this Turkish coin and she bought it. The year would have been 1963 or 1962.
