Chris- Interesting... I've never sharpened any coin image in processing so I wonder if it happened during shooting (or if someone else was in the raw file before me)?--Godot13 (talk) 01:06, 3 October 2015 (UTC)[reply]
  • Why does the gold have spots of red? And I don't recall silver forming iridescent oxide layers. Any particular reasons why this one has it? Nergaal (talk) 04:28, 3 October 2015 (UTC)[reply]
    • It is fairly common for silver and gold coins to develop toning over time (unless they have been kept in an air-tight environment or they have been cleaned). Both coins are well over 200 and 300 years old respectively and are in extremely good condition for their age.--Godot13 (talk) 05:27, 3 October 2015 (UTC)[reply]
I knew some metals get the rainbow iridescence but never realized silver does it to. However, I really don't understand how does gold get "toned". You need reaaaaly special conditions to get it to oxidize. I am not doubting the coin quality, I am just worried about staining by some external layer/substance. Also of curiosity, what sort of grading would these get based on how old they are? Nergaal (talk) 06:36, 3 October 2015 (UTC)[reply]
Silver écu – technically AU (Almost Uncirculated) but given the eye appeal it could be graded as mint state. Gold écu – fully struck AU (and its existence for 374 years might partially qualify as a "special condition").--Godot13 (talk) 18:34, 3 October 2015 (UTC)[reply]
