Quote from: UK Decimal + on January 17, 2010, 04:08:08 PMMy full theory is that someone might have heated the coin and then cooled the inner pill using 'dry ice' to shrink the centre. This would create a greater difference in sizes between the heat-expanded outer ring and the ice-contracted inner pill.
Quote from: AJG on Today at 03:12:47 PMI would start with two coins then drill out the middle of one, and remove the ring from the other.Providing the centre of the first coin was still a tight fit in the ring of the second coin, it could simply be hammered back again using a piece of wood to guard the surfaces.
