When I am lucky enough to sell a cel for twice 
what I paid for it, I always say "Hey I just 
doubled my money on a cel", but I don't say what 
the amount was  :-)   She'd let me do what do 
with no problem, for a number of reasons, but I'd 
rather that she not think I'm crazier than she 
already thinks I am...

My daughter does collect cels, but she and I like 
a lot of the same series, and I think that 
there'd be a huge number of cels to sell even if 
they merged the collections.  (No, she could not 
handle liquidating the collection, at least not 
for another few years).

But I got some good ideas from the responses, 
thanks!
