Another question on authenticity

True, I was more referring to the fact, were items are grossly overpriced, sometimes i see even 300-500% markups, which is mind blowing to me. I think a ton of reputable Vcoins sellers have presence on other platforms: Ebay, this is what i was referring to for the most part, where they have regular auctions. I see some Tetradrachms or Alex III or Nero Denari in mediocre state are priced at 500-600$$ on VCOINS

This is what I use. May not be as precise as a fancy digital caliper, but it is close enough, and it will never scratch your coin. You can get a numismatics caliper like this for $5 to $7 dollars.

 

Hi Sallent, where do I buy this?

 

You can buy it here for $4.46

These guys are great. I buy most of my coin supplies from them.

Thank you, any opinion on Schulz coin albums, do these have PVC??

 

I use a caliper like @Sallent shows but it's my wifes. She uses for gemstones, she hasn't collected in the past few years but I try to encourage her to start again, she has a nice collection.
If I have a coin I question I take it to work & use a digital in my toolbox.

@Svarog I don't know about Schultz products but Lighthouse is a good trusted brand. I know there are others but that's what I use. Also airtite brands are good but not sure if they have albums.

 

I see, thanks Smojo...Any suggestions for coin good, high quality cabinets?

 

Honestly, I've seen members post theirs I think some have made themselves.
Would be a good topic to post in the general forum, or chat.
I'm a metal worker but oak, walnut. Not sure about cedar.
Start a thread get others to weigh in on it.

 

I intend to build a coin cabinet in the coming year but a lot of (admittedly very knowledgeable) people on here are dead set against wood because it outgasses and tones coins.

If you want a cabinet solid kiln dried mahogany with water based finish and minimum/no glue. You can find custom cabinet makers online. The Peter Nichols variety seem okay from some reviews I've read and I'm sure you could find others with a quick google search. eBay to find old wood cabinets too is possible. Outgassing decreases some with age I think.

 

Thank you, sir

 

Any good coin trays?? high quality, good looking?

 

Probably getting into new thread territory here but most of the wood cabinets I've seen have the trays built in. If your looking at something less substantial or more customizable for coin trays you can check out some numismatic supply sites like this one.

im sure you have a ruler lying around somewhere thats all ive used, calipers arent even necessary really. The weight is a bit more importante

 

My calipers were about $5 but shipping can be expensive if you're just buying calipers.

My digital scale which reads to the hundredths of a gram cost about $20.

 

Thank you

 

Lets talk about accuracy. I have a plastic millimeter ruler with advertising on it. It is good enough to tell a 16mm coin from a 17mm one. I have two digital scales each claiming .01g accuracy but they are not in agreement on that last digit at all weights and the difference is not the same for all weight ranges. I never have understood how a calibration weight of 100g like the one that comes with most scales is supposed to be of value at 5g or even 25g. I have a coin that reads 0.05g. I wonder what it weighs? Buying a .001g scale might not help a lot. If you are OK with .1g accuracy, either is fine. You are not going to find ancients that are the exact same weight and diameter as all the coins produced the same day at the same mint. Most mints made a certain number of coins from a given weight of metal but were not precise that every coin was exactly the average weight. Diameter is even worse. If a coin was hammered just a little harder, it spread and is a little wider. Many coins are a bit oval so could be 17mm across and 19mm up and down. Yes, you need measuring and weighing devices but don't get carried away spending extra for a high end system. Someone will say you need greater accuracy if you are doing specific gravity tests. Yes, but can you find a chart that will tell you what the acceptable range of specific gravities is for the coins you are measuring? For that matter, can you find a chart giving averages?

Get a ruler, get a scale and spend the leftover money on books or even coins. Data is delightful but knowing what to do with it is better.

 

Hi Doug,
Thank you so much, this is very helpful
