Other Notable “M” Hallmarks

We will close out the “M” box with some very nice examples, all highly collectible vintage pieces. Enjoy.

A favorite of mine and I wish I had more examples, is Mastiff Metals. Iconic hallmark of a Bullmastiff. These are so hard to find and considered tier one bars among collectors. Found in 5 and 10 oz class, albeit hardly ever, you’d be lucky to come across one in the wild.

Around the hallmark are the words “Faithful Guardian.”

Here is an absolute stunning example of a 5 oz class shared from Brian R’s collection. This is as good as it gets

Perfect stamp and no pour character around the face like my example above.
Perfection.
Reverse, 5.06 troy oz odd weight.

Next up is an MSR ingot, a nice old pour with picture frame on both the 5 and 10 oz. Not an easy bar to find, particularly in 5 oz.

The hallmark is found on the reverse side on these. See below.
You can see the MSR at top with 999 purity in the middle and Fine at bottom of bar.

MEE is another neat vintage piece that typically is found in 5 oz class. I like the look at style of these.

Nice toned example. Very unique hallmark. Wish I knew more about them.
Weight stamp on reverse.

Morris and Watson is an Australian refiner that’s been around for years and still in business today. This is a nice 250 gram example.

Love the stamp on these. Very tough bars to find.

Next is a Mehlos Refinery ingot. Classic old pour style.

Beautiful example.
Beautifully toned reverse.

Next is another very cool old pour from MCR Division of Greb.

Really cool old pour from a bygone era.

Last is MSC, that can be found in 5 and 10 oz class. Note this mold is same mold as Doyle’s Mint, RCG, Regold, and a few others.

Love this mold.

Mesa Casting & Refining Inc.

Arizona is another state with a very rich history of silver refining and many highly coveted hallmarks come out of this state, including Yellow Daisy, Arizona Assay Office, and Gila Development Company, just to name a few. For a number of years until recently, collectors were discovering these beautiful ingots with a “Cactus” hallmark, but nobody knew the maker. We finally have provenance. I believe one of the few who has paperwork that goes with the ingots pictured below.

Incredible pieces that have aged like a fine wine. Top bar is 10.28 troy oz and bottom bar is 7.69 troy oz. Look at the bubbling on the bottom ingot. Incredible. Gold toning inside.
Top ingot is thicker. It appears same mold used, but more silver poured on the top ingot, obviously.
Assay paper from 1984. So cool!

Mid South Refinery and Smelters Inc.

Love this old refiner out out of Brandon, MS. Very unique hallmark of a Magnolia flower, which is the state flower of Mississippi. These came predominately in 5 and 10 oz class bars. They are very high premium and scarce today. Here are a few from my collection.

Such a great 10 oz example with patina.
Killer character and lines on the reverse.
Chunky 5 oz odd weight pour.
Nice patina on reverse.

Metalrex

Something about ingots from Nevada. The state has a rich mining history and many collectible ingots have come from this area of the country. I’ve always been a big fan of Metalrex ingots, out of Reno, NV. They came in sizes ranging from 1+0z (very scarce) to 25+ oz. They are not common by any means and have become very sought after by serious collectors. Below are a few from my collection.

Insane toner, 9.82 oz flat pour. This is a type 1 older variety 10 oz class with both hallmark and weight stamp on obverse.
This is dark with purples, oranges, greens. Killer piece.
Patina and pour lines.
5 oz class

Her’s a nice 10 oz example from Brian R’s collection. This is a type 2 10 oz. Note the differences from my 9 oz odd weight above. Thanks for sharing.

Great stamp.

M/W.E. Mowrey Refining

W.E. Mowrey has a rich and long history in the precious metals industry. They started in 1899 in Minnesota and still do business there today. Here is a snippet taken from their website that gives a bit of history.

“The company was founded in 1899 on Robert Street in St. Paul, Minnesota by William Edwin Mowrey and moved to its present location on University Avenue in 1911. William developed a line of dental alloys as an outlet for the gold he refined.  The company has changed ownership four times since its inception and remains at its second location in the midway area of St. Paul.” http://www.mowreygold.com.

They are made beautiful ingots ranging from 1 oz to 20+ oz. They are very rare and hard to come by. Based on style, my guess is they were made late 70’s to early 80’s timeframe. I’m fortunate to own the 3 pictured below. These are keepers!

Phenomenal trio. The bottom 5 oz class is one of my top 10 favorite 5 oz bars in my entire collection.
Check out the lines on the bottom ingot. Wow.


M & B Mining Corporation (Omega)

One of my favorites to collect are the Omega pieces that were made by M & B Mining out of Las Vegas, NV starting in 1969. They were only around several years and believed to have gone out of business in 1974 when the owner passed away. They came in sizes ranging from 1/2 oz (ultra rare piece) to 100 oz. Their small pieces are some of the most coveted currently among silver smalls enthusiasts.

Some beautifully toned 10 oz class first gen Omega bars.
Pics don’t do these justice. The toning is spectacular.
Another 10 oz class later model with the fancy stamp. Very cool piece.
Reverse pic.
4 different 5 oz class examples. The bottom bar is a first gen and top 3 are second gen. Note size of the 5 stamp on top 3 bars. Big, smaller, and smallest “5” in weight stamp. Fun to collect the different variations.

Here is a family photo shared by Jon M. of his 1st gen Omega pieces. Very nice!

Fantastic!

Notable “L” Refiners

There are not a lot of refiners from this box, but below I’ll showcase several, some more known that others.

First up is Liberty Mint, which are typically found in 5 oz (there are multiple 5 oz varieties), but very scarce in 1 oz and 10 oz class.

5 oz class Liberty piece. These are under appreciated in my opinion.
Note the common square with a line going diagonal on the reverse. You will find this mark on 1 and 5 oz Liberty pieces.
Cool hallmark on the 10 oz class. Liberty Refiners. Liberty Mint. This is the reverse of the bar.
This is the obverse of the bar. I wanted to showcase the hallmark above first.

Next up is one of my favorites, L.C. Murray. These came in two varieties, with Torch Hallmark and without. We can call these type 1 and 2. I think the non hallmark came first. Below is a non hallmark type 1.

Nice type 1 with picture frame. I have the 3 oz version that I’ll post at a later time with my “smalls” collection.

This was my first 10 oz class with hallmark of Torch, but I sold it a few years back. I miss it. These are incredibly rare and command extremely high premiums. Note the long serial number on the back. Very interesting.

Next is a 10 oz class Louisville Metals Company ingot. These are typically only found in 10 oz class, but I have seen one 50 oz variety.

Really unique style on this LMC.
Lot/Serial # on reverse. Pretty cool piece.

Next up is a very rare 5 oz class LCR with Bell hallmark. I’ve only come across 5 or so of these in all my time collecting. They are serialized and were made in very limited quantity based on the serial numbers I’ve seen. They are really neat pieces an very expensive if you are fortunate enough to have the opportunity to buy one.

This came from Ken Conaway’s collection. Very lucky to have it.

#0079 on the LCR.

Another set I collect is the Lawrence and Sons ingots from Mohave, CA. These are fantastic and very tough to find. They come in 1, 2, 3 and 5 oz. I have the whole set now, but will feature the other pieces in my “smalls” posts. I’ll try and get a family phone up, as well.

Beautiful old pour.

Last up is a mystery, but regardless, a fantastic piece. I’ve seen this listed as LCE, but the special thing about this other that the killer style and hallmark, is it matches exactly the mold of the 5 oz Comstock Mine pieces.

This pieces is super toned. The pics do not do it justice and there was a lot of sunlight in this photo. Really love this bar. I have the 3 oz version, too. It’s somehow related to the Comstock mine.
Killer old pour. Purple toning.
