to check if its a blank, try to weigh it and compare it to the normal weight of a cent. also make sure it is the same size. I'm not sure if theres anything else that can definitely tell you if it is a blank. as for cleaning, never clean a coin, but you can soak it in 100% pure acetone for a few days and lightly use a toothbrush on it.

The green won't clean off the coin. If you use something acidic on it, it will turn pink and ruin the collectability of your planchet. So I would leave it alone.

Some verdicare would help the slightest minute amount possibly.

First question, since you are posting from the Great White North, is it a US 1c planchet or a Canadian 1c bronze planchet?
If it is a Canadian unstruck planchet, cleaning it really does not matter a whole lot (the mint actually cleans them in big barrels with ball bearings before striking, in Canada). Verdicare should work, but sometimes it is hard to get up here. Try a long soak in WD-40, then see if anything green and soft can be gently removed with a hawthorn or a bamboo toothpick. I would not necessarily recommend this method for actual coins that have been struck, but 1-cent blank planchets are often perfect for cleaning and restoration practice, since they are so common.
PS - I'll let some US folks chime in here as well, before moving this thread to the Canadian forum sometime in the next day or so.... (looks like a Canada Type 2 blank to me).

It is possibly a 1980-1981 Canadian 1-cent planchet (which normal weight around 2.8 g).

A blank is a circular piece of metal that has been punched out of a sheet of metal stock. After the blank has been through the upsetting machine, it has a rim on it. That is the difference between a blank and a planchet. Your example has a rim, so it is a planchet, not a blank. Some people refer to this as a blank planchet, but it is still a planchet.
