PocketSomeone has compiled a collection of the most popular coins and the theoretical cost of a 51% attack on each network (given the recent Bitcoin Gold and Verge attacks) and what it would cost per one hour attack cost.
Here's when Dogecoin creator Jackson Palmer realized the site crypto51.app was setup to show projected costs each blockchain/network might undergo for bad actors.

The data is pulled from a few resources, like hash rates from MineTheCoin.com and of course CoinMarketCap.com for prices, then rental pricing is based on NichHash.com rates.
