There is just the one decanter currently in this section.

I have seen a certain auction site report that this 10 year old is one of a set of three (the others being a 15 year old & a 21 year old version) but I have never seen such decanters.

The age of the bottle is classified as 'Early 1990's as the label tag on the decanter has the same branding as the 10 year old bottles from this era.
