What do I have here????

China, Kwangtung Province, Year 18 (1929), Y-426, but "possibly" a pattern of a higher denomination. Always give diameter in mm when asking for a coin's ID.

Edit//20 cents denomination; roughly $5 to $10. If copper or brass, "possibly" #Pn-25, a valuable pattern; it really doesn't look like a silver 20 cents, especially with that red coloration in front of the portrait.

 

Just slightly smaller diameter of our quarter...thanks!

 

What about the metal? Unquestionably silver, or copper/brass? The patterns that I mentioned are big bucks. From the size, it's definitely a 20 cent piece.

 

Has more of a "silver-ish" ring than brass. I assume it may be a fake or very low quality metal components.

Does the minor lamination at 2 o'clock give a clue on composition?

 

Here is the page from the Krause Catalog, your coin at the top, and by chance, the various patterns listed below. The pattern #Pn25 comes into play, any off-metal example of your 20 cent coin, Type Y426, Year 18.

But don't order your new Corvette yet...

 

OK interesting....what's my next move???

 

The key is whether your coin is silver or some other metal. I've told you everything I know, and perhaps more.

I still think the red patches on both sides are seldom found on silver coins.

 

I'm not seeing anything that screams silver to me... at all. Am I missing something? Also, it looks like some lamination on the head.

 

Agreed, plus the coin does not strike me as counterfeit, although anything's possible. One thing the OP could do is simply spend $5-10 on eBay and buy another identical coin, and compare them, especially the weight to hundredths of a gram. That would help. In fact, thinking about it, that's what I recommend.

I just looked, there are 14 listed from a couple of bucks clear up to $140 for a slabbed MS-64. I searched for "China Y426," in "Coins," that's all.

 

What is the fineness of the silver content?

Mine looks nothing like the ones on feebay. At least color wise!

 

An authentic coin has a fineness of 70%.

Please provide an accurate weight in grams.

5.35/5.36 grams...keeps going back and forth.

 

Authentic coins weigh 5.4 grams so your coin would be in the correct range.

The diameter should be 22.5 mm.

From your images, however, the coin seems to have a copper patina.

I did a quick check of a few Chinese websites and all their specimens definitely have a silver appearance.

Does not sound like silver coins with similar silver content (Mexico .720 or Netherlands .640).

More brass sounding.

Does the copper ones weigh more?

 

Good luck! This is where I turn the proceedings and commentary over to Gary or any other Chinese expert. Hope it proves to be the rare pattern worth a couple grand. I'd still buy another cheap example off eBay, regardless.

This just occurred to me -- the red patches "might" be where the coin was previously chemically-tested to determine metal content? At some point, that previous owner died, the heirs assumed a Chinese copper coin was worth 50 cents, and it was tossed in a box of common bulk foreign...?

 

Interesting. What compounds would turn silver that color we are seeing?

 

I've see 35% silver nickels with lamination but can't remember seeing any higher silver content coins with any? Is that just me?

 

Does your coin have a reeded edge?

Gary

 

Yep...reeded edge.
