I do not buy expensive coins (although I admire all that I see here greatly. One can only dream!). I do apply Renwax to most of my coins to enhance their appearance. I have never sold a coin - so I am certainly not trying to hide anything from anyone.. just trying to bring out as much detail and eye appeal as I can. Sometimes it does wonders.. sometimes not so much. It can also be removed without much fuss. Here are a couple of "before" and "after" shots. The first is the seller's picture and then mine after application. Not the same photography setup - so not truly "apples to apples" but I can assure you that in hand both depictions are/were very accurate. I can also state that quite a few of the coins I have purchased already have wax applied and this fact is not mentioned when describing the coin. Does not bother me at all - but would that be an issue for the more experienced/high end collector? How do you feel about applying Renwax to coins? Before: After: Before: After: I have many more examples.. but these are the latest additions... Cheers!
