British Half Crown Expanded Shell Set
Regular price $50.00
Notice:
The coins are circulated and aged, they are not new.
The version is George VI.
Limited set, 30 sets only.
This expanded shell set uses actual King George VI British Half Crown coins which features a portrait of King George VI on the obverse and a coat of arms on the reverse side of the coins. Classic and beautiful.
The coins measure 33mm in diameter, perfect for those who feel that Half-dollars are too small but Morgan Dollars are too large.
The coin shell is made the same as the Artisan Coin shells, with low degree of deformation, good fit, high closure, and coverage.
What makes an excellent Shell?
We have proposed four criteria to measure the quality of a coin shell.
-Closeness: The gap between the edge of the Shell and the edge of the coin. The smaller the better.
- Fit: The degree of adhesion between the coin case and the surface of the coin. The better the fit, the better the quality.
-Coverage: The degree to which the edge of the coin shell covers the edge of the coin underneath. The more coverage the better.
-Degree of deformation: The coin needs to be flattened in order to expand the coin shell. During this process, the deformation of the pattern is as minimal as possible.
To improve each criterion requires consideration of many factors. The reason being there are contradictions between each of these criteria.
For example, if you want more coverage, you must make it deeper. However, if you make it deeper, it will cause losses in the degree of deformation. In the production process, it is very likely that to enhance one criterion, other criteria will be affected. There is a delicate balance to be struck.
