Article: If a vendor uses these terms online, at a store, or during an auction, you'll have a good idea of what quality to expect. Mint condition means that the piece is not cracked, chipped, or broken. This antique is in perfect condition. Excellent condition means that the piece has some minor flaws. The antique may have small chips or has been repaired over time. Good condition means that the piece is in a presentable state. Antiques in good condition may have noticeable cracks or chips, and they might require repair after you buy it. The less common an antique is, the more likely it has a high value. Rare items may have been made in limited amounts, or the amount of the items may have decreased over time. Items that are difficult to reproduce in the contemporary era (such as items made of limited materials) are especially coveted among collectors. Rarity could also be determined by a manufacturing abnormality (like an unusual glass color for a certain era) or, in the case of art, an uncommon subject matter for a certain artist. Rarity raises the value of a piece alongside desirability. Some antiques, such as a certain edition of a book, were initially commonplace. Decades or even centuries later, their desirability increases because of their historical significance or scarcity over time. When looking at an antique, you may not know how to tell if this is an authentic piece. Research the antique and check for signs of its authenticity. Be on particular lookout for artist signatures, materials used, and era markers. Even if an antique looks old, it might not be from that era. Really convincing hoaxes use old materials to create their pieces. When in doubt, enlist the help of an antique broker or specialist. If your piece has bronze mounts, unscrew one. On antique bronzed pieces, there will be two colors on the back: the dark, oxidized center and the tiny rim of gilding in the front. If your bronze mounts have a gilded back, your piece may be authentic. Even small chips can lower your antique's worth from mint to excellent (or excellent to good). Examine the item thoroughly and look for any cracks, chipped paint, or other signs of wear. Research what mint condition looks like for your antique and compare to spot any small damages. If you collect furniture or other wood items, look out for wormwood damage. These will look like little holes in the wood. The older the wood, the more holes you'll see. Wormwood damage is not necessarily negative: it can be a sign that the object is as old as the vendor claims. After you have bought an item, bring it to an antiques collector who can tell you how much it's worth. Before the appraisal, prepare a mental inventory of where you found the item, how much you paid for it, and any other information you know about the item. This will help the appraiser assess its worth accurately. Some auction houses have "appraisal days" where they invite people to bring their antiques and have them appraised for free or a reduced cost. Check local auction house websites and mark appraisal day dates down in your calendar.

Problem: Article: Prepare the airgun before you expose the mink from its trap and before you attempt to restrain it. Do not load the gun until the animal has been restrained. Release the safety only when you are prepared to fire. Use two plywood combs to push the mink firmly against the cage's side or roof to keep it still. You want to keep the mink still in order to make an accurate humane dispatch shot. Hold the gun's muzzle a couple of inches away from the mink's head. The gun barrel should be perpendicular to the skull. Avoid aiming at the centerline of the mink's skull because it is very strong. A single shot should kill the mink. If a second shot is required, fire as quick and as safely as possible, aiming for brain stem located where the skull and neck meet. You can tell if the mink is dead if it collapses Other indications are if the carcass is tonic (meaning the muscles lock and contract) or relaxed. If the mink has a fixed, glazed expression and no corneal reflexes, this indicates that it has been dispatched. Convulsions may occur after a lapse of one minute. Once you have confirmed death, unload the airgun and put the safety on. Check your local ordinances and trapping regulations to find out how to dispose of the carcass.
Summary: Use an airgun rather than a firearm. Restrain the mink. Aim the gun. Shoot the mink. Confirm death. Unload the airgun and check the safety. Dispose of the mink.

Make a point of approaching the professor after the class to say a quick "hello" and introduce yourself. Let the professor know you are excited about their class and look forward to learning from them. Mention your name and try to chat with the professor about your educational interests or background. For example, you may say, "Hi, my name is Selena Gomez. I'm a second year med student. I'm looking forward to taking your class." Most professors will hold office hours outside of class time and like it when students make the effort to attend them. Go to the professor's office hours to introduce yourself one on one. Come prepared with a question or thought about that week's class. Bring along notes from class so you can discuss them with the professor. Having notes will give you something to chat about during the office hours. Most professors have open office hours, or office hours by appointment. Show up on time for your appointment with the professor so they are not kept waiting. Be friendly to the professor when you spot them walking around campus or in the hallway between classes. Say "hello" to them at social events on campus. Doing this will let them know you are open and friendly. You may try some small talk with the professor when you see them and they do not seem in a hurry. You may say, "How's your day going?" or "Great to see you."
