Raypadua, I will have to dig to find individual pics of crates. I tend to like collecting the local companies to my area in southern Ontario. Reinhart, Wilson, Moran, Adanac Beverages, Woodlond, Kitchener Beverages to name a few but also have many national brands. To be honest though I have no idea which are or are not valuable. I wouldn't know what to look for. For me I have them to display and they look cool.T Hanks JKL! Just an easy clean and wash and let them be. After cleaning I was thinking of clear coating them with verathane or something along those lines. We'll see.
50 or 60! That's a lot! You should post some pic's of them especially any rare or hard to find ones. I am currently on the look out for Fruit/Mason Jar crates
