<p>[QUOTE=&quot;K2Coins, post: 1431244, member: 30168&quot;]i forget how we did it last year except i know that i did it over a Bunsen burner and used a liquid to soak the coin in and then added another type of metal in order to remove the copper.&nbsp; After that you had the choice to add another metal which would change the color of the coin to gold... i have no clue how it was possible but it just was.&nbsp; And after the process the coin is still in its original state (without the copper though!) except if you kept the coin under the Bunsen burner for to long then the coin would actually melt and distort the shape. Thats all that i can remember... hope it helps!!![/QUOTE]</p><p><br /></p>
