While collecting Irish coins, the first step is to check the year the coins were made. Next, verify the provenance of the coin. This can be done by verifying its measurements.
The diameter, weight and thickness of the coin should be measured and compared with the coin dimensions given. Next, the coin?s edge needs to be checked carefully. If the coin has a seam, then it is not authentic. The third test is the ring test. The sound when the ring is dropped should be same as that of an authentic coin. Before buying the coin, it is important to do an adequate amount of research to ensure your investment is a wise one.
