Nope judging by the OP's post history I think when he is saying "physical coin" he is talking about the Casascius Physical Bitcoin he have purchased which makes sense on why he will be confused on the tax implications on it. Basically @OP you have 2 things to consider when you will be selling back this Casascius again the income you will get from the sale and also the capital gains you will have assuming that the Casascius physical Bitcoin you have is not empty. The income is of course the selling price you have sold it minus the purchase price when you have bought it and also minus the market value of the Bitcoin inside it that will be considered as your income. While the capital gains you need to conisder is similar to that but you need to take account the market value of Bitcoin when you have purchased it and also the market value of Bitcoin when you will sell it. Remember that Income tax and also Capital gains tax fit in this criteria since this is not only the digital asset we need to consider but also a physical item that you have bought.
