I just wanted to hear what they sounded like and had to go through the whole tube. The guy at the coin shop recommended i dont get them if i dont trust the lack of ping. He also stated that some coins may not ping due to microcracks. We weighed them and they were all close enough, but i did notice that chink coinage varies more in weight than any other mint. The yellow jews lack the fine scales and quality control for mint consistency.
The ping test is also used for grinding wheels. Learned this back in the day, if the grinding wheel pings when struck, its not cracked, if it doesnt, it could break during use because of internal cracking.
