Experience I've been in the 3D/2D CAD industry for 10 yrs. & also had the opportunity/exposure to operate with several mainstream design packages. I've assisted many firms facilitate their 3D migration process.
Answer Som, just about all mainstream cad platform can accomplish this. All you need a hi-resolution image of the coin & import this image in Autocad or Solidworks. Find actual/physical diameter of coin at highest precision using a micrometer. Use this number to 'rescale' imported image (diameter) in mm. In Autocad, precision can be measured up to 0.00000001 mm.
In theory, by just referencing the coins diameter precisely as posible, you should be able to interpolate any other dimensions (images/alphabets) inscribed on the coin by using simple distance queries in the software.
Hope this helps!
