Thematic threads

Hello,

Many of us do thematic collections and occasionally create threads related to those themes. However, they often get buried under new posts and are difficult to track. I propose here to post links of thematic threads on both french and english sides of the site, and to keep it updated.
Don't hesitate to post links that I'll put in this message and when you like, to revive old thematic threads with your coins.

Hope it is useful, and happy collecting !

Hi Zac,
Thanks for all that.
I was mainly thinking of threads related to coins. So I did not add the TV, favourite songs or pets. Those are something else.
Cheers, André

Hello,
Thanks for sticking that on top
Hope it helps.

Many updates.
Just added the Islamic world that somehow I had missed.

Some updates including the fascinating "common planchets".

I remembered this one about "chess" themed coins:

https://en.numista.com/forum/topic42517.html

I'm honestly thinking of starting a thread about reptiles on coins, but I can't really think of any (beyond some featuring on modern circulation coins from tropical countries).

There are a few. Ex. the NZ Sphenodon or Australia 2 pennies for the most well known, New Guinea crocs, several tortoises and turtles etc.
Scroll through the animonnaies !
Sure a thread would be nice but not with links, with people own coins

@ZacUK
That site is genuinely interesting, never even knew some of the animals that were on there had ever been on coins.

Now I'm thinking about starting one for plants on coins instead.

​Hello. Already in the list under the heading "History".

Is there a thread for "dead' countries - countries that no longer exist like the Soviet union and south arabia?

Ready to jot down a draft of the thematic thread. A thematic thread is defined as: A metaphoric element, literary or cinematic device used within a film to weave an underlying message or theme throughout the story.

How about my thread on the Halfcrowns - a popular coin used in many British territiories.
(En Anglais) sorry!

https://en.numista.com/forum/topic96500.html

A history and discussion of the large and popular coin used between the 1500s and 1970s featuring the collection of Moneytane and also a place for you to show your halfcrowns.

Its 30 pence worth of fun.

Hi!.

Did we have any kind of thematic thread about "places/monuments/etc that appear on coins that we visited somehow"?

My Topical/Themed collections... Link: https://collectivecoin.com/spirityoda

New guy here! I heard a couple of folks mention reptiles and amphibians.

Well, I've been collecting numismatics for just shy of two months. Not counting art rounds, exonumia, and a few historic coins (mainly CW dates), my primary thematic collection (reptiles and amphibians) is up to just over 100 items. I can see Coins Anonymous in my future, lol.

I'll probably do a blog post once I amass my own photos, but in the meantime, if anyone besides me finds such an endeavor interesting, I arranged them into visible collections.

Coins (75 coins • 37 countries):

One comment, about the 10 Florin (Aruba) bill, Green turtle is "Tortuga Verde" in Spanish.

Hi,

 

first post here, apologies for the many things I will have done wrong, please be kind… :-)

 

I sure am a real newbie, not sure if I'll be a coin collector, its a bit uncertain, therefore this post:

 

My Great-Great Uncle had 25 20 DM Gold Reichmarks in his estate, his legacy got divided and subdivided, and I ended up with 5 of them. My father collected a few silver dollars (canadians) and a gathering of other coins, including a gaggle of 999 silver medals (coins without denomination). In the 70s, I collected German coins (about a hundred 1, 2, 5 10 and 50 Pfennig pieces from 1948 Bank Deutscher Länder plus about another 100 5 and 10 DM silvercoins. When my father passed away, he bequeathed ½ of these and his stamp collection (1950s-2000 with a few before) to me. The coins and the stamps were his way to make me inherit some thing, and I like the idea. In a way, historical coins are not really ‘mine’, I just hold them for others coming after me.

 

I have no great sentimental value for the stamps and wanted to sell them and buy a nice coin for it. I also wanted to sell the lower-value coins and buy something nicer for this, so that offspring have an inherited collection of coins, but not that consists of 100s of pretty much worthless coins. On the stamps, I found no market for them at all. about a dozen stamp shops and stamp auction houses looked at them and said “nope, sorry, go away”. The harshest comment was from a grumpy stamp seller suggesting that if I wanted to have a nice memory of the stamps, I should use them to start a bonfire, make a spitroast and remember forever how nice that one tasted. 

 

My efforts to sell the lower-value coins was unsuccessful as well. I was told:

- the 5 and 10 DM commemorative pieces can go to a German Bank and they'll give me face value for it. So no appreciation over 50 years.

- the Bank Deutscher Länder are probably worth their weight (copper etc)

- the medals have been sold to a coin dealer for their silver weight

 

I still like the idea of (starting) a coin collection, but it seems the market has completely dropped out of stamps, and unless you have stamps already worth a lot, you'd be trading in a community that is gradually dying out, so that the idea of stamps as a way to preserve value for later generations is gone. 

 

Here my two questions:

1. why should I buy coins as a value maintaining thing for later generations? If I can't sell the lower-value ones, and if stamps have lost that value-maintaining thing and are being traded amongst a diminishing number of people, is there anything that would be different in collecting and preserving coins? Is the coin market like whiskey where the value probably increases over time but in either ‘case’ the good barrels are worth hanging on to? Is the coin market like a second-hand car market with old and cheap bangers going to Peru or are scrapped and sold with some models gaining ‘oldtimer status’ that holds their value? 

 

If the economic value of coins are not at all preserved, I might as well put money in a savings book and offsprings can buy themselves whatever they want.

 

And of course, I ‘appreciate’ the emotional, historical, cultural value of old coins, and do enjoy the beauty of coins. I'm neither a brute, a thug nor an imbecile. 

 

2. If there is a market for higher-value coins that means their value is probably preserved over, say, the next 30-50 years, then what would that market be? 

• if it is bullion and such likes (bars, Krügerrands, Sovereigns etc), is their value not very dependent on the current raw material prices? Prices for precious metals are very high today, and I probably would be better off to buy later.
• I don't think it is in commemorative coins, as their price is again very closely linked to the prices of their underlying metals.

 

So my idea would be to start a collection of historical gold coins, say Gold Dukats or coins of the German Kaiserreich, average value say £700-1500. They look good, have some history to them and their price is not as dependent on current metal prices. But that would only come after somebody has assured me that there is value-preservation is some coin collecting segments.

 

I hope I have not completely spoken out of terms and have not offended anybody. (I donated the stamps to a local stamp collector who will sieve them and pass them to his mates. He agreed that collecting stamps has no value preservation anymore, but he enjoys it and that's good enough. I gave the stamps (1000?) to him with a happy heart. Made his and my day). But if somebody could share reflections on coin collecting and its long-term economic impact, I'd be delighted.

 

Many thanks!

Walter

Hello, fellow ccollectors. If any of you has a specific theme of coins to swap, please let me know. Also I can give many coins from almost all topics listed above.

Just ask, because I alway want to get many and many swap partners. As you can see I am newbe
