What to buy for the 10th wedding anniversary of the couple who have everything?

[MrsSpoon]

I thought a big bottle of posh champers all wrapped up, DH thinks something more exciting. We have been invited to their 'do' and it's a bit posh.

Any ideas?

A bottle of vintage wine from the year they met / got married?

11.Joseph Perrier Brut Cuvee Royal Vintage Champagne 1996 £69.99

Form the outstanding 1996 vintage, this delightful Champagne has depth apparent on the nose, excellent bubbles. Good, full searing acidity and a good length. A lovely 10th anniversary gift. Drink now - 2009. This vintage Champagne is shipped in a deluxe silk lined hinged presentation box with four wine accessories (corkscrew, wine pourer, drip stopper & wine stopper [worth £14.99] at no extra cost.

I'd get something to correspond with the 10th anniversary. It's tin or aluminium.
Look here for suggestions.

The wine looks really good Thomcat. I know they like wine. Will show that site to DH.

Also like the idea of buying a share in something and getting a framed certificate on cupcake's link. A bit different.
