Change is the name of the game... out of necessity we need to make a slight design change to the PCA membership pins. 
Problem
We've had continuous problems with the pins tarnishing. Cleaning the pin has also been a bit tricky since it shouldn't be dipped or soaked because of the agate & copper.
Solution
Our local jeweler/co-designer recommends we go to a black background (see photo). Personally, I think the new look is quite attractive & the blackened background makes the wording appear crisper.

All future PCA pins will have the black background. So, if you'd like your pin redone (blackened) please send your pin to:

Michigan Technological University
Attn: Carol Argentati
Educational Opportunity Dept.
1400 Townsend Drive
Houghton, MI 49931
(906) 487-1827

I will ensure that you get your same pin back ... only in better condition. If you have questions, feel free to contact me.
