For ages the military coins which are also known as military challenge coins are popular amongst people. Some people like to collect them as a hobby and some as a fashion. It has been seen that there are several types of military coins available which are used by the different rank holders in the military. Those coins are used on the collars of the uniform. The military coins are tagged in a special way so that they catch attention of the spectator. This is a kind of portrayal of seniority or accolade earned by the military officer by virtue of his service to the armed forces or in any special mission for the country. Bearing a military coin is considered as a pride.

The origin of these coins in United States of America can not be traced to a very particular date. The origin is still debatable. There is very less evidence in this regard about the origin of the military coins. However there are main claims from several institutions as the introducers of the coins. But the most commonly held opinion about the introduction of the coins is credited to United States Air Force. It is told that the coins were presented by one lieutenant to his colleagues as mementos and since then the tradition of military-coins started.

By the President of the United States there has been declaration of several racks of military coins at many instances. These are also called challenge coin because this challenge coins run as a tradition and is a very usual way to assure that the members of any specific squadron is carrying the coin. This is not only pride but also an identity of becoming a member of a particular group of soldier in the military. The norms of such a challenge do not have a formal method or norm for a unit or battalion. The norm may be different between organizations.

However the challenge only applies to those members when they have been appraised by a coin formally by the unit. A possibility of some conflict may arise when members belonging to different organizations initiate challenges among themselves but it is not recommended formally. The challenge can be made any time when the challenger draws the military coin and slap his or her coin on top of the table of a bar. However if it is very noisy then the coin can be rapped on a surface and that initiates a challenge. At times the coin may drop accidentally out of the hand but accidental dropping is also considered as a challenge because they feel it has been dropped deliberately to all present members.

The interesting thing is everyone being challenged has to produce their organization’s coin instantaneously. If anyone failing as such will have to buy a round of drinks to all the members present who have their challenge coin as well for challenger. But if everyone present shows the coin then the challenger has to buy drinks for all.

To know collectible antique glass you must understand how glass was made in the days from which your collectors clamor. Blown glass was made by molten glass placed on the end of a glass tube and blown up like you blow up a balloon. As it was being blown, it was shaped by various tools and when complete it was allowed to cool. During the making of collectible antique glass bottles, a handle may be applied by pressing the molten glass shaped like the handle onto the jar once it started to cool. Occasionally this process resulted in a crack in the bottle, which does little to detract from the current value of a collectible antique glass.

During the fashioning of blown glass, a tool called a pontil rod was used to hold the glass while it was fashioned into the desired shape. In the end it was simply snapped off and may be polished clear, but the evidence of the pontil mark should still be visible and gives a general idea of age and value of collectible antique glass.

In later years glass objects were made of molded glass and many of those were counterfeits of original blown glass. To find modern molded glass masquerading as collectible antique glass there are a couple things to look for like the wear factor. Look at the bottom of the piece first to see if you can find the pontil rod scar and then look for wear marks. If there are marks where there shouldn’t be, it’s probably a fake.

Another hint is small irregularities in the top of the piece, indicating spill over as if too much molten glass had been poured into the mold. This would be a sign of shoddy workmanship, as would too many bubbles in the glass. Although, even in quality blown glass a few bubbles may appear, but in the cheaper reproductions it won’t take long to find them. Perhaps your first step in buying collectible antique glass should be the purchase of a collectible antique glass magazine or book. It will usually identify the collection trends and help lead you on the right collectible path.
