白銀成色鑒定口訣




見joe兄閉關,又係我口水尾天王出場[鄧腳]的時間喇。

見大家呢期講開白銀成色問題,小弟早排提過的書-黃金白銀常識及識別,有寫到白銀成色鑒定口訣,及不同成色的白銀外表及特性有何分別,以供大家參考。

謝Gordon師兄分享, 萬分感謝, 惟獨要要領會當中的聲音, 還需自行領悟, 大家可在youtube找找, 應有所獲

my point is: if you do not believe, do not buy, no need to doubt real or fake when you have already have them at home! it is like after u eat poison, then you doubt if its poisoinous or not! someone suggest to hear the sound! come on! how do u define it real or not by hearing? what is the sound of real? what is the sound of fake? same sound from different people can be different! how do u judge? how can you define a 99.99 or 99.9? or 99? sounds can be same , but very different in value! if we need to doubt this from a national based mints, shall you disamble an ipad or iphone and examine their parts ?? !! do you examine the threads in detail before u buy a clothes? this is beyond reasonable doubts! please do not waste time on this nonsense !

已經學習了..
因為當年有位老教授教我如何分別"袁大頭"銀幣既真偽,如果用吹既方法的確係得既,不過要衡量聲音的柔和,如難用文字講番出黎...

fr Gordon....Could you define Rachmaninov's piano concerto no.2 is not 柔和? 你是如何衡量這首曲不柔和呢.....
exactly!!! 如何衡量a same sound from different people? some people may have hearing problems...his undersatnding may be different from your undersatnding! his perception might not be teh same as yours!

Gordon 提到...

In my view, I think that it should be basic skills for gold & silver bugs. Certainly, I trust national based mints in this stage, but how about in future when the gold & silver rise to moon? We might not buy gold or sliver products from licensed shop or could be tested by instruments every times from internal market, such as Ebay.
An example is someone left message in this blog in past regarding of his friend bought fake silver bar from street vendor and give him for a gift. He suspected it, but he has not enough skill to evaluate the purity of it without suitable instruments.

For one more an example, I can hear the different musical instruments at different positions from Hi-Fi, but my friend cannot define them.
It is art. Could you define Rachmaninov's piano concerto no.2 is not 柔和? 你是如何衡量這首曲不柔和呢?

好難講得清楚..所以我無諗住講得好清楚..
以下只係我盡量講一講我d經驗而已..
真銀幣如果成色足,以及無加入其他金屬..佢吹出既聲音,5會高(過於高音),亦5會低音(低沉既聲音),而係會好柔和(即係不會刺耳,亦不會啞聲)揚長(你可以聽到既聲音可以維持較長既時間)。
我所講既,都係對比假銀幣而言。
當然,我講緊既係"袁大頭"辨別聲音既經驗,當時既銀幣既含銀量,係無今日既銀幣含銀量高。

所以我所講,只係我既經驗而已。
