What do you mean through Colin Cooke, or this site. Surely you mean: Selling could be done through this site (www.predecimal.com) or perhaps another reliable coin dealer like Colin Cooke, for example. I'll gladly sell your set Vitamin, if you can get it to me fully insured, and will allow me 10% commission (which will include all ebay fees). I'll also knock up great pictures of it, and describe it thoroughly and accurately, in order to maximise its sale price. Many people have sold through me, and all are satified.
