You don't need a specialised macro lens - those are way too expensive for what you need. There are some superb compact cameras with macro modes : my Lumix FZ38 goes to 1cm, while my Lumix LX100 (a far better camera) goes to 3cm. You could pick up an FZ38 on eBay for under £100. Here's one for £70: http://www.ebay.co.uk/itm/Panasonic-DMC-FZ38-12-1MP-Digital-Camera-Black-/131388348951?pt=UK_CamerasPhoto_DigitalCameras_DigitalCameras_JN&hash=item1e975b1a17 Obviously, to focus at 1cm, or even a bit further away, you need your light source close to the coin. You could instead use 'Macro zoom' mode, which allows you to focus close while the camera is further away, e.g. 1 foot or even 1 metre.
