How to submit journal entry for sale of fixed asset that appreciated in value?

I have recently sold a fixed asset that appreciated in value.  On all my other sales of fixed assets, I was selling at a loss.  Example, on sales where I received a loss, I entered a credit $100.00 in the Fixed Asset account, then I entered a credit to category Cash Account of the sales price $80.00, and then a credit to category Loss on Disposal of Goods.  In this case the cash received in the sale + the credit to loss account = the original fixed asset price.  

Now that I've sold a fixed asset that has appreciated in value, how do I structure the journal entry, as the credits and debits need to equal out on the journal entry?
