what I dislike in modern semi-numis bullion-
These are my biggest pet peeves when it comes to collecting moden semi-numis bullion-
1- milk spots
2- toning on the rim of silver coins
3- brown spots on bullion gold
Those are my top 3 irks, pet peeves. That said, I realize that imperfections are going to happen no matter what, it happens due to many issues, the environment, how they are handled, the manufacturing process and more.
That said, I think most of us, when we look through our collection, while this is unavoidable, we really strive to have our collections immaculate and other collectors, should we go to sell our collections are also going to be looking for these defects.
So here is what I have learned and tried to avoid-
1- Know which bullion series are problematic. Almost all mints suffer issues with milk spots. Canada has got to be at the top of my stay away from list. I would never collect any single bullion canadian silver coins for risk of milk spots for toning issues. China also has those issues, Mexico, Perth, US Mint, to name a few.
That said, I am leaning more and more towards buying
Perth Mint products, it was refreshing to read on their blog from about a year or two ago how they want to address the issue, tackle it and do their best to minimize it. That instills great confidence in me as a collector and I will be collecting more
Perth Mint products.
2- I never buy slabbed silver bullion coins, if I do, I buy proof silver slabbed coins, I go for the 69 grade. Why go for the lower grade? Many times at auction, the 69 grade can be had for less than the issue price, so you have some money and get the slab to protect the coin. Furthermore, should those nasty milk spots show up, and they can even on proof and reverse proof coins, at least you wont get crushed when you realize that the silver coin is not a PF70 anymore.
Gold bullion slabbed coins I feel more comfortable with. Yes, they too can get toning and even brown spots but they seem to be less abundant Again, I have bought some MS69 slabbed gold coins at auction that I picked up for LESS than if I bought the same coin unslabbed for say a Buy It Now price as an example.
3- Know what dealers you are buying from. Know their terms. Make sure if you buy a slabbed bullion coin, that the dealer accepts returns. Always ask in detail about the condition of the coin.
Random points-
Another point I want to make is that even smaller runs of semi-numis bullion coins have issues. The Rwanda wild life series has milk spot issues. Again, really no silver coin is going to be 100% safe from milk spots.
When buying from dealers, if they have, say old stock of say a popular bullion series, keep in mind those coins might be rejected coins that could not be slabbed due to issues such as toning, milk spots. Often dealers will have auctions with semi bullion coins from say 8 years ago and these coins will not be in perfect condition. Ask an advance of their condition.
Try and buy directly from the mint in some cases, especially from short run semi-numis bullion coins which will help insure you get a coin in the best possible shape- Remember that Benin series that start with the Benin Elephant? My first coin in this series I bought from the dealer who was behind the series in Europe. Came with no toning and no issues to this date.
The second year I bought from a reputable dealer on
ebay. But here was the catch- this dealer was selling what would be considered rejects of the coins, as I come to find out, all the coins had toning on the rim. Furthermore, it was not just that Benin series. Also the Chad Protection of Nature series, roughly translated, also has the same issues with this particular dealer. Buying directly from the mint or main dealer who has authorized the production of the coin is usually a safe bet to buy from.
thankfully the dealer had a return policy and was open when I asked if they had any without the toning on the rim. They told me all of the coins in that series has issues with toning on the rim.
IF there is a series you love but are worried about milk spotting, maybe buy an entire roll, if you can. If its sealed and in a tube, should you sell it, the buyers will not really care so long as the tube is sealed.
Its a tough road and sometimes no matter what you do, you will discover issues in your bullion coins. In that case, just remember it happens to everyone, all of us. I know in my case, I have some bullion coins from all over the world that are going over 15 years old and have nothing on them and then I have some that do.
anyways, I hope this helps new semi-numis bullion collectors!
