I forgot to tell you -
I couldn't find marbles - a set of Chinese Checker marbles - in any local stores, not even in a national toy store chain. (They also don't carry Frisbees!).
I remembered that several years ago I had located on the internet a marble company, a very small business, in Pineville, Missouri. I looked and, thankfully, they were still in operation. I ordered two sets of lovely marbles, as shown in this photo of theirs, and received them promptly. So, if you have lost yer marbles and need to replace them, look here at MarblesMarbles.
