Need help selling an old Gon Bops bongo

Hi,
I'm about to eBay this set of Gon Bops bongos and would like to know how much I should ask for it. They are walnut and the only flaw is where a previous owner drilled a hole through the bridge - exactly through the GB label where the model # is shown. I can't tell the date it was made. From what I can see of the label the model number starts with the letter "I" and other than a few scratches the the drum is in great condition. The shells are in round and no cracks. I'll post some pics.
Thanks,
Chappy
