collecting champagne tops

[Barry]

Hi. I'm collecting Champagne Tops, known in French as 'plaques de muselets' or 'capsules de Champagne'. I collect the tops from all sparkling wines, not just genuine Champagne.
(I also collect crown caps from beer, soda, etc. - but that's another story...)
I'm talking about the little metal cap that protects the champagne cork from being cut by the wires - those which are lithographed, printed, or embossed.

If anyone reading this is willing to keep champagne tops for donating to my collection, I'll be very grateful. I can also use duplicates for trading.

Thanks!
