The French mint (Monnaie de Paris) currently offers the 2001 Monaco euro
set BU at a relatively low price: EUR 29.26 w/o sales tax for non-EU
customers, EUR 34.99 incl. sales tax for EU customers. Limit: 1 set per
order. The sets are supposed to be available in September.

Note that the set may not be listed in each "language interface" yet; I
saw it on the French pages.
