<p>[QUOTE="Jillian, post: 3571073, member: 104446"]Wow, what a thread! I see it has been 9 months since the last post, but I hope some of the experienced coin collectors on this thread will still see my post and be able to offer me some guidance and suggestions on a BIG coin preservation project that I am about to undertake as a total newbie! Let's start with a few sample photos in <a href="https://photos.app.goo.gl/M98G4dxqeGgY8Xwf6" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://photos.app.goo.gl/M98G4dxqeGgY8Xwf6" rel="nofollow">my Google album</a> for reference.</p><p><br /></p><p>During my 40 years on the planet, I have mostly purchased new gold and silver coins, rounds, and bars for wealth preservation, so numismatics is a new area for me to explore. I did a lot of research over the past week because I had an opportunity to purchase a large coin collection (mostly circulated coins) from a woman who lost her husband many years ago and finally decided she was ready to let go of his belongings. The coin collection was an unexpected bonus, as we were just there to purchase some machinery from his woodshop!</p><p><br /></p><p>Anyway, she had no interest in or knowledge of the collection, so she just wanted me to make her an offer. I took pictures of all the album pages and other individual pieces in the collection and put together a spreadsheet of values based almost exclusively on melt value because I was in no position to say whether or not any of the items in the collection had any numismatic value -- I could guess based on some information I found on the web, but those were still pure guesses. Additionally, some of the silver coins in the extremely old plastic album pages showed a greenish tint or residue and I had no idea what that would do to the value.</p><p><br /></p><p>I ended up purchasing the collection at a discount from melt value (about what she would have received had a metals dealer been willing to purchase it from her: silver spot price less a typical fee charged by metals dealers).
