On the plus side, it is not soldered into the frame, so the mount should be relatively easy to remove without damaging the coin. On the negative side, it will probably still show scratches or other signs of having been in a mount, and it definitely has been cleaned, so it will not get a straight grade. The NGC World Coin Price Guide shows this issue to be worth only melt value in all grades, but with a mintage of only 200,000, it would seem like it would be possible to get slightly more, if you could find a collector interested in it. That may not be the case, however, since the 1950 100 pesos, with a mintage of only 20,000, shows the same price estimate. Apparently there is little demand for Chilean gold, numismatically speaking, at the moment.
