I know this is a hot topic for a lot of people and I hope to give a unbiased look into it. I don't know any sellers personally or contact them other than a payment. I can say generally on Ebay you mostly come across lots of coins that have been looked thru. The have been cleaned off enough to tell some details of had coins cleaned to tell the period they came from. Many are just lumped culls and beat up items. That is not to say you cant get a lucky few in groups. Most Sellers also know they must give a few decent coins in groups to avoid getting ugly feedback. Usually these nice pieces are mostly clean and put into the pictures to entice buyers and show there are a few decent pieces in the lot. This is a group that just arrived today from Hungary. I purchased 40 "uncleaned" coins right at $1 each. 42 came in the package. (Group 1)Sellers Photo. (Group 1)These are the pictures directly from opening the package. I noticed about 6-7 show most if not all their details and will have good details after a minor cleaning. In defense of my above statement: you can notice most you can see details of the bust and reverse. The ones that are cakes I can see some dings and bent ones. Are they Uncleaned most yes. have they been searched or gone through I would have to be of the opinion yes. Im sure they were mostly cleaned off and weighed to see the types, then briefly canvassed over for any rarities or nicer pieces of value. I will leave the seller positive feedback as the most you can expect on Ebay is this. But I surely offer to the Ebay novice or bulk uncleaned/unseached buyer that this time can be used sparingly and if far from the truth. the second group is a group of 165 pieces I purchased from a non ebay seller website I had heard good feedback from. He charged about 1.45 per coin over 100 pieces. I obtained 165. 168 arrived. (Group 2)the website picture. (Group 2)The next pictures were taken as received and then after being rinsed down with water. These also appeared to have a lot of nice details each about a top layer of dirt with a small group being encrusted. I have cleaned several and there are some decent nice pieces. I tend to be of the opinion these are also scanned over but not with the scrutiny in regards to Ebay lots. In the 3rd Group from the same website seller I purchased partially/pre-cleaned (mostly) desert patina LRB coins. (on a side note I find desert patina to be dirt and not really patina) these coins you can see all the details and there are really no surprises. For his store it is unknown what you will received but I believe he tries to be fair and give you decent pieces. There were $20 each. So here you can see the steep price increase. (I am assuming fro the work done, the premium details and "Desert Patina") I was pleased with what I got but keep in mind the pricing. (Group 3)Sellers website picture. What I received from the package pictures will be added to the next reply to this thread. As you can see this is just an example of what I have seen on Ebay and from Private sellers on their websites. My recommendations: 1. Don't expect to get rich, find rare, silver, or Gold coins. It is not bloody likely and your only disappointing yourself. 2. Ask questions of sellers before you click the button. Quality, the amount of work involved (Cleaning is not a 1-2 hour thing for 20-100 coin lot). 3. If its too good to be true it is. Have realistic Expectations. 4. Ensure the pictures posted are what your buying. Standard used pictures are quick way to disappointment. 5. This is a process for people who enjoy cleaning and being the first to see the coins after centuries and to have the thrill of doing it themselves. Trust me if you clean a coin from scratch you will appreciate it. I cant stress enough that this is a tedious time consuming effort. If you rush it you will damage your coins. All in all i'm pleased with what I bought and you can be too with the proper research and expectations.
