[Jacob-list] Copper deficiency?

[Linda]

I came across this fleece on ebay - advertised as "w/silver stripe."  You can see the listing at: http://tinyurl.com/32bhpm
Would you think that was a sign of copper deficiency?  Or perhaps some other deficiency or stress period?  I've had two fleeces over the years that showed a very faint gray stripe in the dark wool (nothing like the fleece on ebay).
