Shock and Dismay!

OK, I have been hand sorting pennies for about 4-5 years. At my peak I was only doing maybe $50 a week but over the course of that many years, it still adds up. Plus my two sons do it too. Combined, we have a pretty good stack.
Now, lately I am down to just $10 per week. My average over that 4-5 year time span hear in southwestern Virginia has been a steady 24% copper. Never, NEVER have I been skunked. I went to the bank for some family banking duties day before yesterday and I had a spare $5 bill with me so of course I get 10 rolls. 2 of them are CWR and 8 are Brinks shrink wrap rolls. Keep in mind, I always have very good luck with the Brinks rolls copper wise and wheat wise too. But in the 8 Brinks roll - ONE STINKING COPPER PENNY!!!!! One copper out of 400 pennies. Basically a skunk - for the first time in the years I have been doing this, I felt a complete let down. So, does this mean that Brinks is cranking up the copper capturing or are there just more searchers in my area? I don't know and this is just the first time this ever happened but, for those of us who actually have fun searching, this was no fun at all.
I wll not stop though. The search will continue. Bythe way, the CWR were nice - 30 coppers in 2 rolls.
