If you missed it, Reddit recently announced some major planned changes to Reddit Gold. It's pretty vague and confusing, but my summary was:

The current gold system is basically:

• When you have reddit gold, you can disable ads and have access to a few extra features.
• You can buy gold for $4/month or $30 if you buy 12 months at the same time. You can also buy "creddits" for the same prices, which are basically stored months of gold and can either be used on yourself or to give gold to other users.
• Giving gold to other users is called "gilding". You can gild individual posts on the site, which puts a gold icon on that post and gives the author a month of gold.

Now, from what I can understand, this is the new system:

• Reddit gold is now called "Reddit Premium". You can buy it for yourself for $6/month. There are no bulk discounts any more, so a year of Premium will cost $72. Existing subscribers can keep their current pricing as long as they're subscribed before the change.
• When you have Reddit Premium, at the beginning of each month you will be given some amount of "Gold Coins". These Coins can be used to give "awards" to other users' posts.
• You can give 3 different types of awards to a post, which each cost a different number of Coins:
  • Silver Award - costs the fewest number of Coins; adds a silver icon on the post; the author receives no further benefits
  • Gold Award - costs more Coins; adds a gold icon on the post (same as current icon); the author receives some small number of Coins (not Premium)
  • Super Gold Award - costs the most Coins; adds a "spectacular" icon on the post; the author receives a month of Reddit Premium
• Gold Coins will be purchasable in bundles separately from Premium, pricing not announced.

Today they released more info in /r/lounge (here's the post if you have reddit gold to be able to view it). The summary of the new post is:

• "Super Gold" has been renamed "Platinum"
• If you have any creddits, you have the choice to convert them to months of Premium membership before Sept. 10. If you don't, they'll be converted to 2000 Coins per creddit.
• You get 700 coins per month for having Premium.
• The awards that you can give to posts have these coin costs/benefits:

And there will be the following "Coin Packs" available for purchase:
