If you want to complete the Guild Membership Core Contract, you must find and deliver a Silver coin. However, where to find said Silver Coin is not clear in Marauders. Luckily, you can find Silver Coins if you know where to search when raiding. That said, one great way to find Silver Coins is to search the dead bodies of Raiders. Raiders on the Terraformer Raid map have a high chance of having Silver Coins inside their inventories in Marauders. However, for the best possible chance of finding a Silver Coin, you must also search other locations in Marauders.
Other locations to find Silver Coins in Marauders
Other locations where players can find Silver Coins include Jewelry boxes that occasionally spawn inside containers. You can also sometimes find Silver Coins spawning inside vaults and behind closed doors in locked containers. But, to get inside vaults, you need a blow torch, and to open locked containers and doors, you need a lockpick.

What can you do with a Silver Coin in Marauders?
Once you find a Silver Coin after a hard Raid, you can use it to complete the Guild Membership Core Contract or sell it. Silver Coins can sell for a decent amount, but we recommend using them first to complete the Guild Membership contract. After you complete the contract, you can safely sell any more Silcoins you might come across while playing Marauders.
