The first category of fake coins isintended for the production of counterfeits in circulation. The profit from thesale was obtained by assigning the return on counterfeiters of these coins (thedifference between the production of fake coins and its nominal price). In somecases this difference increases by reducing the content of precious metal (goldor silver fake coins) or by replacing the precious metals by copper, bronze orlead-tin alloy with drawing on mask coverage of the corresponding color orsilver electroplating.
Coin fraud is an unfortunate reality in the coin collecting marketplace, but you can avoid buying fake coins, and avoid coin fraud in general, by learning how to spot fake coins.
Avoiding coin fraud boils down to one basic point: knowledge. If you want to avoidbecoming a victim of coin fraud and avoidbuying fake coins, you first need to learn what the genuine coin looks like. On this site you can see and also purchase some examples of Russian coins of different periods (Peter I - Nikolay I, Alexander II - Nikolay II and Soviet Coins). Then it's just a matter of making some comparisons and employing a little bit of common sense. This is a main tip before making coin collection. Sometimes in our time of high technologiesmaking some comparisons ofgenuine coinsdoes not work toavoidbecoming a victim of coin fraud and we need to look for better tips toavoidbuying fake coins.To give an example, I'll use a fake silver coin types that is being produced in large numbers at last time.
What can you say of these Russian 1 Rouble (Ruble) of Ekaterina II coins? Are they original or fake coins?
Rouble coin of Ekaterina II, 1775 - averseRouble coin of Ekaterina II, 1775 - reverse
Rouble coin of Ekaterina II, 1777 - averseRouble coin of Ekaterina II, 1777 - reverse
I do not want to disappoint you but these are fake coins.Spotting this fake coins andmaking some comparisons withthe genuine coins you can say is that they do not "look right" for some measures :
1.Fake silver coins may or may not have a silver-plated finish on them. Although higher-quality struck fakes might look pretty convincing if they are plated, many fakers don't even bother to plate the coin. Silver has a distinctive sheen to it that is neither too harsh nor too soft or "soapy" looking.
2. Ona fake silver coin types that introduced very pronounced blurred numbers of the years (1775 and 1777)looking with almost no relief.
3.Eagles and letters look soapy and dull with someblurring edges of bumps (looks like it was casting and not minting).
4.Most fake silver coins are made from silvery metal alloysthat weigh less or more (silver-plated lead) than genuine silver. Weigh the coin in question: if the weight is wrong for the type, it is a fake coin. For some cases in our time of high technologiescoin frauds may choosemetal alloys with the same weigh of original silver coin. Thus the technique of size checking in home conditions is important too (diameter and thickness of the coin).
5. At a laboratory conditions with an appropriate equipment spectral analysis showed that in rouble 1775 silver 94%,and in rouble 1777 at all 98%, while the original coins silver 84-85%.
As a result when compared step-by-step to a genuine silver coins, the coin fraud is obvious.
There are 4 technologies to produce fake coins1. Etching
2. Stamping
3. Casting
4. Electroplating
