Right now, I can order a 66lb "Happybuy" anvil for $153 with free prime shipping. One assumes that the $153 includes the cost of shipping it all the way from China in the first place.
For comparison, a similarly sized anvil from a reputable local dealer costs $949 plus tax and shipping at the lowest rate (UPS standard) is $93.

Tungsten doesn't seem especially heavy; it's a little less than gold.
It's not the heaviest thing in the world, but it's probably the heaviest thing a person could buy a practical cube of. The main metals heavier than lead are gold, iridium, mercury, platinum, tungsten, and uranium. Uranium is a comparable price and density to tungsten, but buying iridium is gonna be at least 50x the price for something 10% denser.

Out of curiosity, what kind of weights were they? I was under the impression that it has been phased out of many uses because of high toxicity (including via skin absorption when handling it)
Does lead actually absorb through the skin? I always heard the main pathway was getting lead dust on your hands and then eating/inhaling that.
Since I discovered the availability of anvils on Amazon, I have always wondered about the economics of shipping them. Right now, I can order a 66lb "Happybuy" anvil for $153 with free prime shipping.

Depends how you measure it. Any X kg/lbs of matter here on earth is still that same X kg/lbs everywhere in the universe. Assuming the scale being used to weight is correctly calibrated to whatever planet it's in, it would still show up as the same amount of kg/lbs.
Depends upon what you set out to measure. lbs is specifically a unit of force. kg is specifically a unit of mass. It is a category error to equate these as measures, although (in many places) an everyday convention to do so on Earth . IIRC the English unit for mass is the slug . If the tecnical limit is 70lbs or so, that is must technically be read as lbs force -- aka force of gravity which varies with location.
Incorrect. The avoirdupois pound (lb) is historically a unit reflecting the long conflation of mass and force, but the modern unit of that name is expressly a mass unit that is a derived unit of the kilogram. The corresponding unit for force is the pound-force, (lbf).
This isn't useful for USPS box packaging; I just think it's neat.
edit: Also, inertial confinement fusion plasmas go up to about 1,000 g/cm³,

An implosion-type nuclear weapon can compress matter to some multiple of the density of osmium.

When I heard that the crypto millionaires were buying Tungsten cubes for fun, I checked into the prices. Amazon lists a 1.5" cube (weighs 1 kg) at $199 and a 4" cube (that weighs 18.9 kg [0]) at $3499. There's no way I'm spending that, but I will admit to wanting to experience their density for myself.

I wish I was a millionaire. I could fulfil my wish of owning replica of IPK that is small cylinder of Platinum-Iridium weighting very very close to kilogram.

Uranium at it's elemental density is a comparable price to tungsten??
