3-Ball Shirt is pointless to give to anyone... Golden shovel is easy to get...
Alot of people have them. Sorry, but begging for Bells won't exactly get you
very far... If anything, trading rares for bell amounts will. Or you can also
try turnip trading. Buy a decent amount, and wait until Tom Nook has a good price for them. But don't wait too long, or they spoil. (Buy on Sunday, Sell by Saturday)
Best prices I've seen/heard of, are 400 Bells and 500 Bells.
Try and sell whenever you see 100+ Bells being offered by Tom Nook.
Anything Lower is a waste.
