Got any donation letters? What's your oldest?
Lemme check my inventory.
Lets see here, I've got one from -2000...
Here's another I never got!

And another!
And here's one my friend gave me after he stopped giving me things....
Oh, and here's one that contains the same properties of the imaginary world I visited to get it on an imaginary adventure.
And this one I got from donating with imaginary money and hence its also imaginary...
So...that adds up to...
Zip.
EDIT: -cough- Though, I could toss something over, say, this demonic pendant. Seeing as how...you're a demon, you probably have scores of those though. At the time I bought it it was only 5k. They sell for a lot these days. I've essentially just had it as a sign of (weak) power.
