I have been waiting for almost a season for a rabbit's foot to drop off my rabbits. It has been the last thing needed to complete the community center for a while now.
There is another way to get those...
Inside the desert dungeon the flying eels have like a 2% drop rate on them. If you farm them with some luck food you can usually get one in a day or two. The travelling sales cart also sells them occasionally.
There's no silver in Stardew Valley. Only copper, iron, gold and iridium.
Ugh. I don't know why I kept calling it silver. Every time I typed silver I meant Iron. Dunno what's wrong with me!
