With less then 20 percent of the
bars left un-redeemed, this bar
is among the most elusive and
valuable of the Casascius bars.
‘1000 BTC’ and ‘One Thousand
Bitcoins’ is laser printed on the bar
(in the same manner as on the 500
BTC bar), instead of stamped like
on the 100 BTC versions.
In February 2014, Casascius sold
a redeemed bar on eBay for 3,850
USD, with all proceeds going to the
Electronic Frontier Foundation.
The lower image is actually of an
unfunded bar, but it demonstrates
detail as there are few available
photos of funded 1,000 BTC bars.
