You can break the jackpot and not only digging in the ground, said the historian.
Over the past 35 years, several countries and empires have disappeared from the political map of the world. New states appeared. And they all had coins. They deserve different things, different years of release, different mints of release. Some had a marriage, others in the carelessness of the mint workers were released on a different metal basis. For example, they had to use a copper-aluminum alloy to issue 1 cent coins and issued them on silver-nickel as for 10 cent coins.
Somewhere a spikelet on a coin was shot down, sometimes instead of three spikelets there were four, instead of 15 ribbons 17 and all these mistakes ... this is money for collectors.
A coin with a face value of 1 cent can be sold for 100 or even all 1000 dollars. Interestingly, all these coins are in common people's pantries, they can be found in parks, flea markets. They sell them for 10 cents and they can be sold to collectors for hundreds of dollars and some especially valuable copies for 10,000 - 20,000 dollars.
The same applies for example to old manhole covers, sometimes the price can reach $ 550 for a manhole of the end of the 19th - beginning of the 20th centuries. Prices also have old rails, which can sometimes be seen sticking out of the ground in 19th century building sites.
Previously, rails served as strengthening the foundation of houses, rafters, fasteners for telegraph poles. The houses were already demolished, but the rails remained. Sometimes you can read them - the Belgian Railway in 1867, sometimes the French Republic of 1888, the Imperial Railway of 1898, the Austro-Hungarian Empire in 1878 ... and these rails also cost money, they are bought at auction for $ 400-800 .
There are those who understand the old days, in china, German or Austrian ... sometimes in flea markets you can see them. Where are they from? These are trophies from the second world war. Previously, one could meet old German cars, motorcycles and bicycles. But in the 90s, almost all of them were exported abroad and there they were sold for tens of thousands of dollars.
Less often, breaking old houses in them find trophies from the Second World War, sometimes from the First World War - pistols, machine guns, cartridges, bayonet-knives, works of art, ancient books in German dating from the 14th to 16th centuries ... Someone brought them from Geramania after war ... and then could not attach. And the veterans of the war did not hand over the weapons to the police, for some reason they left to themselves ... but then their descendants still surrendered these weapons to the police, as the media write.
Sometimes at the flea market you can find an icon, a mug, a pen, a watch ... it costs a cent and sell them for hundreds of dollars.
It would be nice if these finds were in the museum, we would learn more about our history ... but ... now all finds are on the market ...
Also, regarding old stamps ... but I'm not very good at this topic, but for example, in our mountains in the World, sometimes rare stamps can be found on envelopes of the 40-60s. The Germans came to us, scientists, having seen such an envelope, this scientist in exchange gave it to my neighbors - a new digital SLR camera and laptop.
Probably those brands were worth it ...
