What Are Some Of The Most Underappreciated And Undervalued Foreign Coins?

In terms of underrated, I'd say Hong Kong, and straits settlements coinage are one example that comes to mind. Not the most extreme example but very low prices for most pieces below AU+

In general, I noticed it's when the particular country of the coin starts getting richer and the
local collectors now with more excess cash want to buy back their coinage, that's when the prices
start going up. Case in point is China about 10 years back.

Is this a more or less accurate observation ?

I believe yes. I was going to mention India. And probably a high grade 19th century rouble I bought about 20 years ago is the silver coin in my collection which has appreciated most in that time frame.

SO, unless it's already too late, the countries witht he fastest growing middle classes are:
China
India
Indonesia
Nigeria
Philippines (that one surprised me)

Time to start buying up those nice Philippine coins!

Too true.

British silver coins from Victoria thru George VI are way undervalued in VG thru F grades. The new collectors can't afford coins in VF or better, so buy in VG or F but they're scarce because so many have been melted for scrap.

I expressed my surprise at a recent auction to the dealer who had bought a load of scrap shillings and florins (a florin was two shillings) (grading G to VG) for 70% over melt and he told me he could sell shillings for £5 and florins for £10, any day of the week. That's way above catalogue value in Fine.

If the lockdown ever ends, I'm going to be selling him my low-grade silver.

Many coins are attractive to me, but unfortunately most of them attract little public attention. Now I am paying more attention to Fiji coins. This is a very exotic country and its coins are appropriate, but I am still convinced that they are not appreciated.

I also wanted to mention the coins of German New Guinea. Now they cost about $ 200 or higher. For me, this is too much for me to afford, but you look at their circulation, it is very small. They should cost a lot more

Sleek: it is a pattern coin, not meant for circulation. This is why it's expensive

This would apply to quite a lot of silver coins, like those huge 4-ounce Panamanian 20-balboas struck in the early 1970s. I agree with Pertinax that low-grade British silver is much scarcer than catalog values would suggest.

The Krause catalogs aren't a reliable guide to the values of modern European coins. For instance, Uncirculated 1994 French 5 francs with bee privy mark: US$1.65 in Krause, 110 euros in a French catalog! But of course a dealer outside France would have trouble getting €110 for one!
