I got the standard 1 inch size of these loading pins so that I could put a bunch of my standard vintage plates toward something useful. They do exactly what they are made for and they work perfectly well.

Value is certainly subjective on these. If you are a "weight is weight" kind of person, you should skip these. They are standard sized plates (which you can find any day on marketplace for less than a dollar per pound) but some Lurie addresses are harder to find and thus can go for many hundreds of dollars per plate pair on the collectors' market. But if you love the history of weightlifting, including all the drama behind the early manufacturing of iconic equipment, then these probably deserve a place in your collection. The address plates track the movements of Dan Lurie from his early at-home manufacturing business to his eventual broader commercial enterprise. All of the address plates are collectibles, and when his company got really large they stopped using the address altogether and then eventually the manufacturing was outsourced to overseas. Those later plates are not collectible but the early ones certainly are.

Classic plates that make great users for all your standard bars and other 1" implements. Being small bore, they can often be found at much cheaper prices than the 2" plates that dominate today. I use them for grip training and on my dinnie stone posts.

Collectors love the buns and globes. They are a connection to the bygone Silver Age of physique culture. They are still a ton of fun to push around today, but for most owners they are show pieces more than daily drivers. The 50s and 60s can be obtained for a few hundred bucks per pair but if you start seeking the 5 lb increments, they get really pricey. Not worth the investment unless you're dedicated to the idea of building a complete set. Nonetheless, they will hold their value over the years, due to the rich history... so at least you can count on them being worth something in the future, unlike all that money being taken out of your paycheck to float the Social Security ponzi scheme.

By the end of a workout, when the core work comes around, I just don't feel like lying on dirty hard stall mats. This mat give just enough padding to keep comfortable during floor work but not so thick that it can't be rolled up and stored away readily. Quick and easy to deploy and to remove. The kids love it, too, and half the time it winds up somewhere upstairs because someone has been playing yoga on it in front of their cartoons.

Comfortable to use, stable on the cable work. Great for kickbacks and other leg work. Also very useful outside of the gym. I bought two pairs, because the Dark Witch has four limbs that need to be restrained.

From wikipedia: "Roy "Reg" Park (7 June 1928 – 22 November 2007) was an English bodybuilder, businessman, and actor. His first title was Mr. Britain in 1949. He then won Mr. Universe in 1951, 1958, and 1965. He went on to star in five films. Later in life, he received renewed interest for being the first inspiration (and later a mentor) to Arnold Schwarzenegger." Reg Park plates come from the UK, where they were made in the 1960s. There is also another version with smaller block lettering that were reportedly made in South Africa, where Park lived out his later life. A pair of 45 lb. plates will run you about $400-500 plus the shipping costs to import them. The very shallow and sloping volcano hub makes hub lifting essentially impossible unless you are Brian Shaw. The plate diameter is 17 7/8 inches, so if you put it on the deadlift bar first then normal 17 1/2 inch plates will slide on without a bar jack.

My favorite exercise with these is Oberst Crunches. I imagined doing wall slams with them when first purchased but that rapidly proved untenable when the Dark Witch that lives in the house above the dungeon came unglued in response to the slamming. The minions love trying to play catch with the lighter ones.
