How to earn Silver in Anvil Empires
Choose an active bounty at 
Bounty Board, collect its required trophy and return the items to receive Silver. Check the required quantity and reward before setting out; completing the objective alone is not the turn-in.
Plan the hunt before collecting trophies
Read the creature's attacks and ranges before choosing equipment. A trip after Wolf trophies is a different commitment from approaching Reaver Bandit with a group. Bring the trophy named in the contract rather than assuming every hunting drop qualifies.
Other ways to earn and spend Silver
Vehicle trading and renting Homestead access offer other routes to Silver. Horses and donkeys must be well fed before listing them at the Marketplace, and a livery fee applies. Keep enough Silver for the Avatar you intend to recruit at 
Avatar Recruitment.
