Although this sounds a bit different the pineapple, coke, grape juice and brown sugar combine really well with the ham.
I made this Ham for Easter. I used the slow cooker instead of the oven. The type of ham was a fully cooked Spiral Ham and cooked 4 to 5 hours on low. This ham was moist and a wonderful flavor. My husband loves eating the left overs from the fridge. I will make this receipt again, and again. - 09 Apr 2010 (Review from Allrecipes USA and Canada)
To heyjude615, I bought a bottle of Welch's grape juice and used a cup of that. Made this for Easter dinner and it was delicious. Best ham I've had in a long time. Before making it I though maybe the brown sugar, cola, pineapple juice, and grape juice would end up making the ham too sweet. I couldn't have been more wrong. The sweetness complimented the saltiness of the ham perfectly. I'll definitely be making this again in the future. Thanks for the great recipe. - 12 Apr 2009 (Review from Allrecipes USA and Canada)
My dh's grandmother made her ham very similiar and since I couldn't find her recipe I used this one. It came out just as good, dare I say maybe better?! So moist, flavorful...my picky kids loved it. Even my sil who doesn't like ham loved it. - 13 Feb 2009 (Review from Allrecipes USA and Canada)
