My husband ignited our children's interest in collecting stuff when he showed them his old stamp and old coin collections. Now both of our children collect things like rocks, buttons, bottle caps and such. Here's my son looking at the coins that his Dad collected over the years. We actually looked at the value of some of his collection and some has a high value and some are just average. Collecting as a hobby is pretty cool because you never know if the stuff you are collecting is worth a lot as time goes by.
However, if you really want a good collection, you can invest to an American eagle gold coin and watch your investment go big like a balloon in years. If I have a lot of resources, I would invest into this kind of venture because it can be worth in the years to come. The important thing to remember though, before investing into coins is to make sure that the company you are investing your money into, is authentic. You don't want to be a victim of fraud and believe me, there are people out there that are good in deceiving others. So to make sure that your investment is in good hands, check out the company's standing and reputation in the market.
How about you, do you collect as a hobby? Do you venture into this kind of investment? You may leave me your opinion about investing into gold coins at the comment section.
