Hi, if like this;

Then £2-5 seems to all they fetch I have found, for some reason very cheap compared to similar period stuff.
The earlier boxes go for a lot more, in fact 10 times the price (top left here);

The other two tins are USA sold Bulldog branded, really nice colourful tins but hard to find.
