As a parent I'm guessing there's more to the story than you're letting on. I'd bet this is similar to taking away a video game console as punishment for something you did/didn't do. My son "lost" his PlayStation more times than I care to count.
Tell them about David Bowers. He started dealing coins part-time when he was 15, graduated from Penn State with a degree in finance, has written about 100 books, has been writing in Coinworld evey week since 1962 and is basically the Godfather of coin collecting. Tell them about the good side of coin collecting.
Well that sucks to hear. I hope you get them back eventually unharmed. But if you find joy and a thirst for discovery with coins do not ever abandon that. It is a part of your childhood which is a part no one should ever give up. Good luck.
You are in a tough spot. Thankfully, you can participate on the boards without posting images of coins you may own and can also send private messages to those whom you may want to interact with in order to obtain more information. Good luck.
The thing about parents, is they usually do what they think is best for you. I wouldn't necessarily say what they did is "messed up". A lot of the things that my parents did that I thought was unfair a few years ago, I look back and feel grateful for, because it taught me life lessons and now it makes sense as to why they did those certain things. Appreciate what your parents do, and try to understand their position sometimes, even if you don't like it.
shave your head into a MOHAWK, get your nose pierced, dress crazy. tell your parents you will go back to normal when you get your coins back. see if they like their own game. just kidding (maybe)
Oh wait I did similar the Mohawk the Metallica and iron maiden t shirts etc oh wait I still wear those could be far worse you didn't get arrested (I hope)
Sometimes Moms and Dads don't understand the the passion related to coin collecting that YN's so often experiance. They feel the need for 'book learning' is more important. Truth is, you are venturing into an area that is not mainstream study acceptable.........especially for a young man. They feel your efforts of study should be channeled more to the traditional areas of study. I applaud you, my young friend. You chose to study something unconventional and foreign (in their eyes, and to many others) to the traditional sense. Let not this setback interrupt your studies. "Well....I guess they were pretty mad, as I said that I wanted to be a PCGS/NGC grader at the elementary school promotion ceremony" They never saw that coming. Probably expected you to give a dissertation on quantum physics or something. Give them time. They will eventually realize that there is a Doctorate associated with this hobby..........
I know you're disappointed but hopefully it doesn't discourage you from learning the hobby and sticking around. Heck, I do a whole lot more reading about coins than I do buying. I suppose if I had unlimited funds the gap might narrow some, but I'd still likely read more than buy. Stick around.
Member since July 14th with 422 posts? That's pretty active..............perhaps your parents are trying to quell your "obsession" with coins and posting on Coin Forums? My advice is to talk with them about it instead of running to grampa.
You say "they saw those coins lying around on my desk". I know there were times when my sons weren't properly taking care of some of their possessions , I took them away until I felt they understood, and would take care of them properly. Respect your parents and try to think of their side of the situation, make sure of your priorities and discuss the situation with them and I would bet it will all work out.
Find out what motivates your parent's decision on this matter. Parent almost always are looking out for your best interest. They could be under the perception that there is no way anyone could earn a living off this "little hobby" and have your best interest in mind. My parents hated what I was involved in in high school until they meet someone who worked in my field and saw that you could make a very good living. You stated that you wanted to be a PCGS/NGC grader. Do they know that top tier graders make 6 figures? Keep in mind also, that all successful negotiations start with interest you have in common. Find out their reasons why and see if your concerns can meet theirs.
Ask them what they want you to change in order to get your coins back. Maybe they're afraid you won't have any friends in the future if you spend all your free time with your collection. And seriously, do some sports or skateboarding to show them you've some other interests as well... this works with my girlfriend ;-)
Just search the entire house a day that you're home alone for everything they took, and then hide the items where no one but you can find them. Or best option if it works is obviously to ask why it happened and what can be done to get them back asap. If parents were looking out for their child's best interest (I'm sure yours are), in most cases they would talk to them and make them understand why things should be done a certain way and help them, or at least talk about what each side is in disagreement with, not take away personal belongings. So many better options that have the same or better effect.
