Please take a look at the accompanying photograph of the Antigonus Gonatus (277-239 BC) and let me know what you think. I saw the crusty coin for sale and thought it had promise. The results speak for themselves. Personally, I think "zapping" is by far the kindest way to clean any encrusted coin. The top left and right photographs depict the coin before zapping and the bottom two obviously depict the zapped coin.
If you would like to learn to "zap" coins please join us at CoinZappers. I would never ask you to quit this wonderful membership to join CZ but I ask that you add us to your repertoire of learning experiences. Each ancient coin group has special qualities and one learns from each group. I love to teach and we will be more than willing to walk you through the zapping process.
You have my personal invitation to join. Simply state that "Jerry asked you to join".. The URL is as follows: http://groups.yahoo.com/group/coinzappers
The invitation remains open and you will meet some of the kindest members on the web. I look forward to seeing you at CZ! Let me know what you think of the process. Thank you for reading and God Bless.. Jerry..
