and love it we do! 5 rosies out of two boxes...not bad...not bad at all. that's above average!
as for your book...good luck. i've managed to fill all but 11 holes in my '46-'64 silver rosie book through CRH. i'm tempted to make a stop at a coin shop and swap dime for dime to fill the remaining holes. (would that count as CRH finds as i'm trading found coins to fill the empty slots?)
now...for my newest project i've just purchased a merc book. that baby is gonna take some serious work to fill. already have 16 holes filled. wooohooooo!! but...the 1916-D and the 21's are gonna be tough to find but hey...as you said...that's why we play the game. and it reminds me of one of my favorite sayings, "if it was easy girl scouts would do it."
good luck on all your future hunts!
