So I shouldn't have any problems mixing gold plated berg pins with tin 
plated berg pins as long as they are lead-free?

This project which started out as a simple one has become a major issue. 
There are so many look-alike berg pins and they are not interchangeable. 
I found that Berg Mfg is now part of FCI. The male and female pins i got 
at Fry's do not fit into the rectangular female receptacle from Digi-Key 
that were made by FCI. However the FCI pins will. At a quick glance they 
both look the same, but taking a real close look (In my case I had to 
put on 2 pairs of +225 reading magnifiers) they are different. So much 
for a rose is a rose........
