I remember that there were several high-profile instances of duplicate MAC addresses being burnt into NICs during the 1990s - once every 2-3 years, IIRC. And those were just the ones that were discussed publicly.
D-Link shipped NAT-boxes around 2003-2004 or so with identical MAC addresses (and a "clone your PC mac address to the WAN interface"-functionality). I checked my then employer ADSL network and 5% of the customer ports had the same MAC address, D-Link support alledgedly said something about the MAC address not being "unique enough" and directed their customers to the cloning functionality to "solve" the problem.
