In ancient times, a weighty wallet with an abundance of coins could be estimated only by its weight, because each coin had exactly as many grams as its denomination meant, and it was not accepted to put different coins in one bag. Today everything has changed, coins of the same denomination can have different weights.
All coins of modern use have different weight characteristics. Among other things, over time, the material from which the coins are made tends to wear out or, on the contrary, "overgrow" with unwanted plaque and dirt, and therefore the metal acquires completely different parameters in relation to those that were inherent when leaving the conveyor.
Difference in weight
Interestingly, the weight of modern Russian coins can also vary from indicators such as belonging to jubilee money, the presence of a smooth or serrated edge, etc. Thus, fifty-kopeck coins with various types of edges have a deviation of about 0, 12 grams with an increase towards the serrated edge and weigh respectively 2, 8 or 2, 92 grams.
Coins of the same denomination, issued in different years, may have significant differences in this indicator.
Taking two different ten-ruble coins in hand, it is possible, without any special devices, to determine that the weight characteristics of these coins differ in favor of small-circulation jubilee money. This difference is approximately 2, 55 grams, respectively, the weight varies from 5, 65 to 8, 20 grams.
The difference between the smallest Russian still popular coin - a kopeck, and the largest, with a denomination of 10 rubles, is about four grams. According to the average data, their weight does not exceed 1, 47 and 5, 65 grams, respectively.
A five-kopeck coin, according to official information, should weigh 2.6 grams, a fifty-kopek coin - 2.9, a ruble - 3.25. In fact, such coins may have weight characteristics that are slightly different from the accepted norms.
With the growth of the denomination, the weight characteristics of the coins also grow, so the 5 rubles minted at the mint weigh more than six grams.
Weight limit
There are certain limits of weight tolerance, which determine the possibility of deviation of the characteristics of coins in one direction or another. The higher the technology of minting coins is developed in the country, the less this parameter, while coins that differ from the established parameters in a smaller direction are usually called lightweight, and in a larger one, respectively, heavy.
In addition, it should be noted that the Soviet coins still alive in memory were the standard of precision of execution and standard, for example, one Soviet kopeck had a weight equal to one gram, a kopeck coin - 2 grams, and so on up to five kopecks, which, when weighed, clearly gave out the number 5 and not a gram more or less.
