I agree, who is going to frown upon cleaned 90% junk coins if they are only paying melt? I just watched an auction complete on Ebay for a roll of cleaned liberty halves for 23.6x face value so no, I don't think you are going to get less. By the way, I have cleaned all my coins. I cleaned them in mild soapy water and rinsed them with distilled water. Why? Who knows where these coins have been in the last X number of years. =D I am pretty sure if people can get $20+ x FV on Ebay for culls then my cleaned coins will at least get that. Just to clarify I do not collect 90% for numismatic value.
Besides a limited number of Johnson Matthey 1oz silver bars and a couple of PAMP 1oz silver bars, I only buy Perth Mint, RCM and US mint 1oz bullion. After reading a few stories I am leary of buying bars. I prefer easily recognized 1oz coins instead. I also do not buy of CL either. The local bullion dealers only offer discounts over 50-100oz and at that they are negligible so I just buy a variety. I have been busy the last month so other than junk silver, haven't had a chance to go to a bullion dealer and see what their premiums are. I do know that I lost $125 on the Gold buffalo I bought a few weeks ago...POOH!!!
You bought an ounce of gold and you still have an ounce of gold. Unless you sell it, you've lost nothing.
At my LCS they were at 26$ last Friday. Coin shop guys were saying they could sell them on ebay for $32-40, so really can't do any better on them. I got a couple Engelhard rounds for 2.50+ melt. They had just sold out of ASE's.
$26 is a good price nowadays for silver dollars. I bought a cull Morgan recently for $20, but that was an anomaly.
Cleaning old US coins should be viewed as forbidden. Please don't do that. I personally like the older silver coins from my own homeland. If you are going to acquire silver coins from another country, I strongly suggest picking up a 2013 Red Book of coin values and seeing what you have, one coin at a time. Most collectors value cleaned coins much less than none cleaned coins. Some even prefer coins with obvious evidence of age and circulation. The advantage I see, for me, with pre 1964 silver coins from the US where I am, is when it becomes time to sell them, their value is known and if it isn't obviously a counterfeit coin, an assay is probably not going to be required. Versus a silver brick cast by some 'fly by night' or a not quickly verifiable hallmark which will require an assay before it can be cashed in.
What about cleaning them in mild soap water? Would that affect the value? I just don't like dirty things. hahaha.
if you are not planning on ever selling them and it is just for your personal collection, go ahead and clean them, I say. it is up to you, see what other people say first also
