billion of these coupons were
printed but never issued in preparation for a major gas crisis which
never materialized - and despite the $12.5 Million cost to the US
Government, they were ultimately ordered to be destroyed. Stored at the
Pueblo Army Depot in Colorado until 1984, their destruction was ordered
because of the portrait of George Washington on the front of each
coupon, which was thought to be able to trigger dollar change machines.
Supposedly, all were destroyed - but about 300 of these coupons were
known to have survived.
