I have created a Dapp and am working with a coin shop to allow buying selling collectible coins on the blockchain. The prototype is available on Ropsten at http://www.ethermetal.com
. I have a fuller description at https://medium.com/@cron/bringing-collectibles-to-the-blockchain-1d98e163b445
. I think you could potentially build funds or other things on top of it.
The contract code is at https://github.com/ethermetal/ethermetal/blob/master/contracts/WarehouseReceipt.sol
. I haven't been able to do a standard token, because the items are non-fungible, but I'd like to allow building on top of it.
What do you think?
