Guernsey Varieties

I collect varieties in Guernsey coinage I use the reference book Guernsey Coinage by W.Exley dated 1969. I'm looking for another Guernsey collector who collects by the same reference book who may have a lot of extra
Guernsey coin that may wish to do some trading of coins. Don't want to sell any of my spares but would like to trade for some varieties I don't have. Perferably an older collector who knoks about the coins in W.Exley's book after all there are 11 varieties just in the 1864 8 doubles, 5 varieties in the 1868 8 doubles; 5 varieties of 1874 8 doubles. and one has to buy many coins to complete a set of varieties, Thank
You (Bill) Canac51
