I have two suggestions: Take a look at the paper "Handschoenen getest voor het hanteren van collecties", from A. Brokerhof, S. de Groot, H. Baija, CR 2004 (ICN,Amsterdam) Evaluate your silver coupons not only visually, but using electrochemical reduction, that can give information about the type of silver compound formed as well as its amount (= rate). For more details about the possibilities of the technique, see: "Impact of environmental conditions on metallic artefacts from the treasure rooms of Reims Cathedral", V. Costa et al, in Heritage, Weathering and Conservation, Fort et al (eds); Taylor and Francis Group, London, 2006, ISBN 0-415-41272-2. I can help you doing some experiments, if necessary.
