Custom Dog Tokens/Coins

I've been having a lot of ideas lately ^^.

How about custom dog tokens or coins? It would be an item that is good for making a dog in the custom tool.

Example:
Custom Australian Shepherd (8 markings) Coin
Custom Border Collie (10 markings) Coin



[Edit]OR just have the coins have number of markings and any of the coins will work on any of the breeds in the custom tool

At the end of creating a custom dog where you enter the name, it would ask if you would like to pay with bones or a coin (will show all your coins in a dropdown list). You need to have the appropriate coin to make the dog.

This could let players gift people customs without having to ask for the markings and therefore ruin the surprise, be a new referral prize (we could use more prizes! =D), or make it easier for the site to award people prizes for site hosted events.

They could either be sold in the monthly shop or have their own special page where they are sold for the same bone amount the custom would normally cost.

For example: Custom Shetland Sheepdog (1 marking) Coin would cost 9 bones just like it normally would in the custom tool.

Let me know what you think =D
