Finds can often be found in old houses built in the 40-50s of the last century. Especially in the city center and not on the outskirts. Since the center of the city, where the original building came from, the cultural layer is richer. Large cities have more ancient history than small ones as a rule. In the center, land has been built up since the 16th century. Then they were rebuilt with buildings ... after that they made gardens on the places of former houses. Which eclipses again gave up for development during the first empire, when Small-An was colonized. Construction was carried out in the middle of the 19th century ... after the house was again dismantled and rebuilt in the late 30-40-50s of the 20th century. Whereas in the suburbs, on the outskirts, until the 50-60s of the 20th century there was agricultural territory and development began only in the mid 60s of the 20th century ...
So when disassembling houses of the 40s of the 20th century, it is worth paying attention to the bricks themselves. Sometimes you can find royal bricks, they are thinner, longer than the usual modern. If you take them in your hand and gently tap your finger, they will ring. Such bricks easily withstand an earthquake of 8 points on the Richter scale. If there is a brand of a plant on such a brick, then it can easily be sold for $ 5 per 1 piece. Usually in a house there are up to 10,000-20000 bricks. Royal bricks without a mark are 5-10 cents per 1 piece. They are bought by wealthy businessmen and built from them, their forks worth $ 200,000 or even all of $ 1.5 million.
But this is so particular.
Next, pay attention to the roof, namely attics, tai usually hide valuables, gold and silver coins, cutlery, jewelry, paintings, prints, trophies from the Second World War. Some simply old things, originally from the 20-30s of the last century. Old records, wineglasses, porcelain ... and at auctions, antiques, for these finds you can earn from a couple of tens of dollars to a couple of hundred. Some plates or porcelain may still be unique and the price then can be up to 4000-6000 dollars.
Also, sometimes in old houses there are beams made of rails. They have hallmarks, usually these are rails of 1858-1898. If you are lucky, it may turn out to be Belgian or French, for 1 rail with a seal and data from the manufacturer, you can easily earn 550 dollars or even all 2500.
It is worth paying attention to the floors, if you raise them, then treasures can be found under them, as well as under the steps of the ladder. In addition, there may simply be coins dropped by the builders there ... also applies to places under the windows, there may also be small treasures.
In the basement, sometimes they hide treasures in the corners or in the center, walled in the walls. Sometimes in the walls, there are walled up with stucco doors leading to the lower floors of the basement.
It also makes sense to check the paths to the house and garden paved with tiles, stones or bricks. There, too, sometimes they find old treasures. Some "especially" advanced peasants hid their money in toilets that were on the street or "garbage pits". But this search is very amateurish.
Some peasants living near the forest, hid their money and jewelry in the hollows, tied on high branches or near the roots.
Some treasures could be found at the bottom of small rivers or man-made irrigation ditches; in summer, spring and autumn, water flows there in a concrete or stone-lined bed. And in the winter, here ... there is no water ... and the treasure is located under the channel, at the bottom, in a pit 10 cm deep. Few people will guess about such a place for storing jewelry.
There are also treasures near pillars or inside mounds of courtyard walls. There were pockets of placers of 10-20 silver kopecks from 1920-1923. As well as two silver rubles in 1920. Not to mention the copper kopeks of 1924-25. If there was a reflink or points on the edge, then such a coin already cost $ 100, whereas a coin without reflex on the edge, it cost only 3 dollars. Everywhere has its own subtleties.
