no one can make that choice other than you, if you want it then go for it, if not then get somthing else or save the money.
Go for it man. Just don't sell out. make sure you get one you will appreciate for a long time. I sold out on my first draped half and sold it last month at a 50 dollar loss.
Really, for me, I would go for it, but not expect much of a return when selling it back. Like JCB said, he lost $50 on his, but it is all about taste.
Buy what you like. Besides, the draped bust coins (IMO) are one of the most beautiful designs out there.
You should aim for the million dollar chain cent and then before you know it you have enough for the draped bust.
