If it were to happen it would have to be at least 1000 coins per gem, as 100 is far too low - that would be a gem per level completed.

They definitely should do something with the coins in this game. We don't need more sprouts and I don't tend to spend much on plant food or power toss etc. I'm not sure they would ever go for buying gems with coins, but if only there was something else in the game you could buy with coins. In the first PvZ I spent a huge amount just trying to complete my zen garden for the achievement. Unfortunately with this game there are too many sprouts for me to even bother buying any with coins and even if there were I would not care enough to buy them.

I think personally its more useful thinking about what other ideas we could use the coins for, as I cannot see them removing the potential revenue stream of people buying gems because they don't play the game enough.
