A few years ago, Tokens and Coins hit upon a wonderful idea, particularly for nostalgic baby boomers: jewelry and gewgaws made from old typewriter keys. As you might guess, those “margin release” and “back space” keys struck a responsive note, and since then, Tokens and Coins has greatly expanded its line to include salvaged goodies from old Scrabble sets, watch movements, Monopoly trinkets, memorabilia from subways and from baseball parks, you-name-it. Among the best sellers are cufflinks made from old fountain-pen nibs (gold-plated sterling silver), Scrabble cufflinks, and assorted key rings. We think the coolest key rings are the ones that say "Floating Shift" -- and we’re sure that all these items are things that Dad will go for. Prices range from under $50 to a few hundred dollars.
