..or know a free site to look stamps up without subscription

No but would be interested in the replies also, I have my dad's stamp collection here.

You could try ebay to see what other are selling similar things for. My dad is obsessed with watermarks on old penny black letters!

How strange. DP and I were talking over the weekend of him taking time off soon to get his grandfathers and mothers collection valued.
